==Features==
===Accounts===
Flickr has always offered two types of accounts: free and paid. Until January 7, 2019, free accounts had up to 1 TB of storage. On January 8, 2019, the account offerings changed.<ref>{{Cite news|url=https://www.theguardian.com/technology/2018/nov/02/flickr-delete-millions-photos-reduce-allowance-free-users/|title=Flickr to delete millions of photos as it reduces allowance for free users|work=The Guardian|access-date=November 6, 2018|archive-date=November 3, 2018|archive-url=https://web.archive.org/web/20181103011339/https://www.theguardian.com/technology/2018/nov/02/flickr-delete-millions-photos-reduce-allowance-free-users/|url-status=live}}</ref> The free option is limited to 1,000 photos or videos stored, with videos limited to three minutes. After January 8, 2019, members over the limit could no longer upload new photos to Flickr. On February 5, 2019, a free account's older content would be deleted automatically if it contains more than 1,000 photos and they do not subscribe to the paid service tier,<ref>{{Cite news|url=https://www.theverge.com/2018/11/1/18051950/flickr-1000-photo-limit-free-accounts-changes-pro-subscription-smugmug|title=Flickr will end 1TB of free storage and limit free users to 1,000 photos|work=The Verge|access-date=November 1, 2018|archive-date=November 1, 2018|archive-url=https://web.archive.org/web/20181101185808/https://www.theverge.com/2018/11/1/18051950/flickr-1000-photo-limit-free-accounts-changes-pro-subscription-smugmug|url-status=live}}</ref> with the exception of content that was already uploaded with a [[Creative Commons]] [[copyright]] license before November 1, 2018.<ref>{{Cite web|url=http://blog.flickr.net/2018/11/07/the-commons-the-past-is-100-part-of-our-future/|website=blog.flickr.net/|title=The Commons: The Past Is 100% Part of Our Future|date=November 7, 2018|access-date=November 10, 2018|archive-date=December 1, 2018|archive-url=https://web.archive.org/web/20181201173927/http://blog.flickr.net/2018/11/07/the-commons-the-past-is-100-part-of-our-future/|url-status=live}}</ref> 

The paid option features "unlimited" storage, advanced statistics, advertising-free browsing, videos up to 10 minutes in length, "premier" customer service, and promotional offers with other partners.<ref>{{cite web|last=Gartenberg|first=Chaim|date=November 1, 2018|title=Flickr will end 1TB of free storage and limit free users to 1,000 photos|url=https://www.theverge.com/2018/11/1/18051950/flickr-1000-photo-limit-free-accounts-changes-pro-subscription-smugmug|archive-url=https://web.archive.org/web/20181101185808/https://www.theverge.com/2018/11/1/18051950/flickr-1000-photo-limit-free-accounts-changes-pro-subscription-smugmug|archive-date=November 1, 2018|access-date=December 6, 2018|website=[[The Verge]]|df=dmy-all}}</ref> 

In May 2011, Flickr added an option to easily reverse an account termination, motivated by the accidental deletion of a Flickr user's account, and public reporting of its protracted restoration.<ref>{{cite web|first=Stephen|last=Shankland|work=CNET| url=http://news.cnet.com/8301-30685_3-20066857-264.html?part=rss&subj=news&tag=2547-1_3-0-20|title=Flickr Adds Account-Undelete Option|date=May 27, 2011|access-date=May 27, 2011|archive-url=https://archive.today/20130922033731/http://news.cnet.com/8301-30685_3-20066857-264.html?part=rss&subj=news&tag=2547-1_3-0-20|archive-date=September 22, 2013}}</ref> Flickr may delete accounts without giving any reason or warning to the account's owner.<ref>{{cite news|last=Jeffries|first=Adrianne|title=On Flickr Deleting User Accounts|url=http://observer.com/2011/02/on-flickr-deleting-user-accounts/|access-date=July 24, 2013|newspaper=[[New York Observer]]|date=February 3, 2011|archive-date=August 11, 2017|archive-url=https://web.archive.org/web/20170811143735/http://observer.com/2011/02/on-flickr-deleting-user-accounts/|url-status=live}}</ref>

As a result of the [[SmugMug]] buyout, Flickr added the ability for users to download all of their account data, such as photo albums, contacts, and comments.<ref>{{Cite web|last=Fleishman|first=Glenn|date=2019-02-06|title=How to download your Flickr photo library and transfer it to Google Photos or iCloud Photo library|url=https://www.macworld.com/article/3153944/how-to-download-your-flickr-photo-library-and-transfer-it-to-google-photos-or-icloud-photo-library.html|url-status=live|archive-url=https://web.archive.org/web/20190227020452/https://www.macworld.com/article/3153944/how-to-download-your-flickr-photo-library-and-transfer-it-to-google-photos-or-icloud-photo-library.html|archive-date=2019-02-27|access-date=2020-08-29|website=Macworld|language=en}}</ref>

On April 15, 2025, Flickr announced to restrict downloads of original and large-size images (larger than 1024&nbsp;px) owned by free accounts since May 15, Creative Commons-licensed photos and Flickr Commons members will not be affected.<ref>{{Cite web|title=Service Update: Original & Large Size Download Limitations on Free Accounts|url=https://blog.flickr.net/en/2025/04/15/service-update-original-large-size-download-limitations-on-free-accounts/|publisher=Flickr Blog|date=April 15, 2025|access-date=April 27, 2025}}</ref>

===Organization===
The images a photographer uploads to Flickr go into their sequential "photostream", the basis of a Flickr account. All photostreams can be displayed as a justified view, a [[slide show]], a "detail" view or a date stamped archive. Clicking on a photostream image opens it in the interactive "photopage" alongside data, comments and facilities for embedding images on external sites.

Users may label their uploaded images with titles and descriptions, and images may be [[tag (metadata)|tagged]], either by the uploader or by other users, if the uploader permits it. These text components enable computer searching of Flickr. Flickr was an early website to implement [[tag cloud]]s, which were used until 2013, providing access to images tagged with the most popular keywords. Tagging was further revised in the photopage redesign of March 2014. Flickr has been cited as a prime example of effective use of [[folksonomy]].<ref>{{cite web|last=Vander Wal|first=Thomas|author-link=Thomas Vander Wal|title=Folksonomy Research Needs Cleaning Up|date=January 17, 2006|url=http://www.vanderwal.net/random/entrysel.php?blog=1781|access-date=September 4, 2006|archive-date=September 9, 2017|archive-url=https://web.archive.org/web/20170909095704/http://www.vanderwal.net/random/entrysel.php?blog=1781|url-status=live}}</ref>

Users can organize their Flickr photos into "albums" (formerly "sets") which are more flexible than the traditional folder-based method of organizing files, as one photo can belong to one album, many albums, or none at all. Flickr provides code to embed albums into blogs, websites and forums. Flickr albums represent a form of categorical [[metadata]] rather than a physical hierarchy. [[Geotagging]] can be applied to photos in albums,<ref>{{cite web|url=http://www.gossinteractive.com/flickrsets|title=Creating Flickr Sets Video|work=Goss Interactive|date=February 26, 2010|access-date=February 26, 2010|url-status=dead|archive-url=https://web.archive.org/web/20100503085216/http://www.gossinteractive.com/flickrsets|archive-date=May 3, 2010}}</ref> and any albums with geotagging can be related to a map using imapflickr. The resulting map can be embedded in a website.<ref>{{cite web|url=http://www.gossinteractive.com/flickrmap|title=Mapping Flickr Sets Video|work=Goss Interactive|date=February 26, 2010|access-date=February 26, 2010|url-status=dead|archive-url=https://web.archive.org/web/20100503085211/http://www.gossinteractive.com/flickrmap|archive-date=May 3, 2010}}</ref> Flickr albums may be organized into "collections", which can themselves be further organized into higher-order collections.

Organizr is a [[Web application]] for organizing photos within a Flickr account that can be accessed through the Flickr interface. It allows users to modify tags, descriptions and set groupings, and to place photos on a world map (a feature provided in conjunction with [[Yahoo! Maps]]). It uses [[Ajax (programming)|Ajax]] to emulate the look, feel and quick functionality of desktop-based photo-management applications, such as Google's [[Picasa]] and [[F-Spot]]. Users can select and apply changes to multiple photos at a time, as an alternative to the standard Flickr interface for editing.

===Access control===
Flickr provides both private and public image storage. A user uploading an image can set privacy controls that determine who can view the image. A photo can be flagged as either public or private.<ref>{{cite web|url=https://www.flickr.com/help/privacy/|title=Public/Private|work=Flickr|access-date=October 1, 2011|archive-date=December 2, 2020|archive-url=https://web.archive.org/web/20201202091113/https://www.flickr.com/help/privacy|url-status=live}}</ref> Private images are visible by default only to the uploader, but they can also be marked as viewable by friends or family. Privacy settings also can be decided by adding photographs from a user's photostream to a "group pool". If a group is private all the members of that group can see the photo. If a group is public the photo becomes public as well. Flickr also provides a "contact list" which can be used to control image access for a specific set of users in a way similar to that of [[LiveJournal]]. In November 2006, Flickr created a "guest pass" system that allows private photos to be shared with non-Flickr members. This setting allows sets or all photos under a certain privacy category (friends or family) to be shared.<ref>{{cite web|url=https://www.flickr.com/help/guestpass/|title=Guest Pass|work=Flickr|access-date=October 1, 2011|archive-date=November 20, 2015|archive-url=https://web.archive.org/web/20151120010138/https://www.flickr.com/help/guestpass/|url-status=live}}</ref> Many members allow their photos to be viewed by anyone, forming a large collaborative database of categorized photos. By default, other members can leave comments about any image they have permission to view and, in many cases, can add to the list of tags associated with an image.

===Interaction and compatibility===
The core functionality of the site relies on standard [[HTML]] and [[Hypertext Transfer Protocol|HTTP]] features, allowing for wide compatibility among [[Operating system|platforms]] and [[Web browser|browsers]]; Flickr's functionality includes [[RSS]] and [[Atom (Web standard)|Atom]] feeds and an [[application programming interface|API]] that enables independent programmers to expand its services. This includes a large number of third-party [[Greasemonkey]] scripts that enhance and extend the functionality of Flickr. In 2006, Flickr was the second most extended site on userscripts.org.<ref>{{cite web|last=Partington |first=Brian |url=http://www.utata.org/ink/2006/18583.php| title=Ink Interview: Steeev |work=Utata Daily Ink |date=August 19, 2006 |access-date=July 27, 2013| archive-url=https://web.archive.org/web/20060831202653/http://www.utata.org/ink/2006/18583.php| archive-date=August 31, 2006}}</ref> Organizr and most of Flickr's other text-editing and tagging interfaces use [[Ajax (programming)|Ajax]], with which most modern browsers are compliant. Images can be posted to the user's photostream via email attachments, which enables direct uploads from many smartphones and applications. Flickr uses the [[Geo (microformat)|Geo microformat]] on over three million [[geotagging|geotagged]] images.<ref>{{cite web |url=https://techcrunch.com/2006/08/29/flickr-supports-geo-microformat/ |title=Flickr supports "Geo" Microformat |work=[[TechCrunch]] |date=August 29, 2006 |access-date=July 26, 2013 |archive-date=April 27, 2017 |archive-url=https://web.archive.org/web/20170427100832/https://techcrunch.com/2006/08/29/flickr-supports-geo-microformat/ |url-status=live }}</ref>

According to the company, {{as of|2009|8|lc=on}} Flickr is hosted on 62 databases across 124 servers, with about 800,000 user accounts per pair of servers.<ref>{{cite web|url=https://www.flickr.com/help/forum/en-us/100485/page6/#reply672723|title=Bad case of Hiccups!|author=Kevin Collins|work=Flickr.com|date=August 16, 2009|access-date=August 18, 2009|quote=For some of the details, we have 62 DBs across 124 servers- accounts are spread across 2 servers each.

Signed-in Flickr users can "Follow" the Photostreams of other Flickr photographers. Reciprocating this process is optional. A user's homepage contains a stream of their Contacts' photos at 2/3 screen size.<ref name="flickrfaq">{{cite web | url=https://www.flickr.com/help/faq | title=Help | publisher=Flickr | access-date=April 8, 2014 | archive-date=December 2, 2020 | archive-url=https://web.archive.org/web/20201202050152/https://help.flickr.com/ | url-status=live }}</ref>

Groups are another major means of interaction with fellow members of Flickr around common photography interests. A Flickr Group can be started by any Flickr user, who becomes its administrator and can appoint moderators. Groups may either be open access or invitation-only, and most have an associated pool of photos. The administrator of the Flickr group can monitor and set restrictions for the group, assign awards to members, and may curate and organize the photo content. Recent uploads to a group will sometimes appear on its members' homepages. Group photo pools may be displayed in the "Justified View" or as a slideshow.

"Galleries" of photos from other photostreams may be curated by any signed-up Flickr user, provided the feature is not disabled by the photo's uploader, these are then publicly viewable.<ref name="flickrfaq" />

Any Flickr user can post comments to a Flickr photo on its photopage, unless this has been disabled by the uploader, and users can "favorite" a photo. A user's favorites can be viewed in a justified or slideshow display.<ref name="flickrfaq" />

Users of [[Windows Photo Gallery]], Apple's [[iPhoto]] (version 8), Adobe's Lightroom 3.2, Apple's [[Aperture (software)|Aperture]] (version 3.0), [[darktable]], and [[digiKam]] have the ability to upload their photos directly to Flickr. They can also automatically update their status on other [[social network|social networking services]] when they upload their images to Flickr.<ref>{{cite web|url=http://blog.flickr.net/en/2010/06/10/flickr-facebook/|title=Flickr + Facebook!|work=Flickr|date=June 10, 2010|access-date=December 8, 2012|archive-date=December 26, 2012|archive-url=https://web.archive.org/web/20121226043950/http://blog.flickr.net/en/2010/06/10/flickr-facebook|url-status=live}}</ref> Flickr provides a desktop client for [[MacOS|Mac OS X]] and Windows that allows users to upload photos without using the web interface. Uploadr allows drag-and-drop batch uploading of photos, the setting of tags and descriptions for each batch, and the editing of privacy settings.<ref>{{cite web|url=https://www.flickr.com/tools/|title=Flickr Uploader|work=Flickr|access-date=October 1, 2011|archive-date=November 4, 2013|archive-url=https://web.archive.org/web/20131104135947/http://www.flickr.com/android/|url-status=live}}</ref>

Flickr has entered into partnerships with many third parties:

* Flickr had a partnership with the [[Picnik]] online photo-editing application that included a reduced-feature version of Picnik built into Flickr as a default photo editor.<ref>{{cite web|url=http://blog.flickr.net/en/2007/12/05/edit-your-photos-on-flickr/|title=Edit Your Photos!

* In addition to commercial mapping data, Flickr now uses [[OpenStreetMap]] mapping for various cities; this began with Beijing during the run-up to the 2008 Olympic games. {{As of|2008|10}}, this is used for Baghdad, Beijing, Kabul, Sydney and Tokyo.<ref>{{cite web|url=http://blog.flickr.net/en/2008/08/12/around-the-world-and-back-again/|title=Around the World and Back Again|work=Flickr|date=August 12, 2008|access-date=November 7, 2008|archive-date=September 20, 2020|archive-url=https://web.archive.org/web/20200920205913/https://blog.flickr.net/en/2008/08/12/around-the-world-and-back-again/|url-status=live}}</ref><ref>{{cite web|url=http://blog.flickr.net/en/2008/10/30/more-cities/|title=More Cities|work=Flickr|date=October 30, 2008|access-date=November 7, 2008|archive-date=August 6, 2020|archive-url=https://web.archive.org/web/20200806122523/https://blog.flickr.net/en/2008/10/30/more-cities/|url-status=live}}</ref> OpenStreetMap data is collected by volunteers and is available under the [[Open Database License]]. 
* Flickr offers printing of various forms of merchandise, including business cards, photo books, stationery, personalized credit cards and large-size prints from companies such as [[Moo (company)|Moo]], [[Blurb, Inc.|Blurb]], [[Tiny Prints]], [[Capital One]], [[Imagekind]], and [[QOOP]]. 
* The Flickr partnership with [[Getty Images]] to sell stock photos from users is under review as of early 2014.<ref>{{cite web|url=http://mashable.com/2009/03/11/getty-images-flickr-collection/|title=Flickr Photos Become Stock Photography at Getty Images|last=van Grove|first=Jennifer|date=March 11, 2009|work=[[Mashable]]|access-date=May 18, 2009|archive-date=September 25, 2020|archive-url=https://web.archive.org/web/20200925163028/https://mashable.com/2009/03/11/getty-images-flickr-collection/|url-status=live}}</ref><ref>{{cite web |url=http://www.dpreview.com/news/2014/03/10/getty-and-flickr-to-cease-partnership |title=Getty and Flickr to cease partnership |publisher=DPReview |date=March 10, 2014 |first=Barney |last=Britton |access-date=March 30, 2014 |archive-date=July 29, 2020 |archive-url=https://web.archive.org/web/20200729132343/https://www.dpreview.com/articles/3703124774/getty-and-flickr-to-cease-partnership |url-status=live }}</ref>

===Filtering===
In March 2007, Flickr added new content filtering controls that let members specify by default what types of images they generally upload (photo, art/illustration, or [[screenshot]]) and how "safe" (i.e., unlikely to offend others) their images are, as well as specify that information for specific images individually.<ref>{{cite web |url=https://flickr.com/help/filters/ |title=/ Help / FAQ / Content filters |publisher=Flickr.com |date=March 20, 2007 |access-date=April 4, 2014 |archive-date=December 1, 2020 |archive-url=https://web.archive.org/web/20201201091412/https://help.flickr.com/ |url-status=live }}</ref> Individual images are assigned to one of three categories: "safe", "moderate" and "restricted".<ref name="Wired" /> Users can specify the same criteria when searching for images. There are some restrictions on searches for certain types of users: non-members must always use SafeSearch, which omits images noted as potentially offensive, while members whose Yahoo! accounts indicate that they are underage may use SafeSearch or moderate SafeSearch, but cannot turn SafeSearch off completely. The system achieves a fairly good separation of family-friendly photos and adult content; generic image searches normally produce no pornographic results, with the visibility of adult content restricted to users and dedicated Flickr communities who have opted into viewing it.<ref name="Wired">{{cite news|first=Terrence|last=Russell|title=How Porn and Family-Friendly Photos Coexist on Flickr|date=November 7, 2007|work=[[Wired (magazine)#Website|Wired]]|url=https://www.wired.com/techbiz/media/news/2007/07/flickr|access-date=July 24, 2013|archive-date=August 20, 2020|archive-url=https://web.archive.org/web/20200820203548/https://www.wired.com/2007/07/how-porn-and-family-friendly-photos-coexist-on-flickr/|url-status=live}}</ref>

Flickr has used this filtering system to change the level of accessibility to "unsafe" content for entire nations, including [[South Korea]], Hong Kong and Germany. In summer 2007, German users staged a "revolt" over being assigned the user rights of a [[minor (law)|minor]]. {{Crossreference|selfref=no|See {{Section link||Censorship}} below.}}

Flickr offers users the ability to either release their images under certain common usage [[license]]s or label them as "[[all rights reserved]]". The licensing options primarily include the [[Creative Commons]] 2.0 attribution-based and minor content-control licenses – although jurisdiction and version-specific licenses cannot be selected. As with "[[tag (metadata)|tags]]", the site allows easy searching of only those images that fall under a specific license.<ref>{{cite web|title=Flickr: Help: Photos: How can I copyright my photos?|work=Flickr|url=https://www.flickr.com/help/photos/#87|access-date=November 12, 2007|archive-date=March 22, 2016|archive-url=https://web.archive.org/web/20160322054129/https://www.flickr.com/help/photos/#87|url-status=live}}</ref>

On January 16, 2008, Flickr launched a program called "The Commons on Flickr."<ref>{{Cite web |date=2008-01-16 |title=Many hands make light work |url=https://blog.flickr.net/en/2008/01/16/many-hands-make-light-work/ |access-date=2022-08-16 |website=Flickr Blog |language=en |archive-date=July 7, 2022 |archive-url=https://web.archive.org/web/20220707071250/https://blog.flickr.net/en/2008/01/16/many-hands-make-light-work |url-status=live }}</ref> Several international cultural institutions share images using a "no known copyright restrictions" through the program. According to Flickr, the goal of the program is to "firstly show you hidden treasures in the world's public photography archives, and secondly to show how your input and knowledge can help make these collections even richer." Participants include the [[National Museum of Denmark]], [[Powerhouse Museum]], [[George Eastman Museum]], [[Library of Congress]], [[Nationaal Archief]], [[National Archives and Records Administration]], [[National Library of Scotland]], [[State Library of New South Wales]], and [[Smithsonian Institution]].<ref>{{cite web|url=https://www.flickr.com/commons/institutions/|title=The Commons: Participating Institutions|access-date=November 28, 2013|work=Flickr|archive-date=April 21, 2014|archive-url=https://web.archive.org/web/20140421184942/https://www.flickr.com/commons/institutions/|url-status=live}}</ref><ref>{{cite news|first=Noam|last=Cohen|url=https://www.nytimes.com/2009/01/19/technology/internet/19link.html?_r=1&partner=permalink&exprod=permalink|title=Historical Photos in Web Archives Gain Vivid New Lives|quote=In a similar move to harness the public's knowledge about old photographs, the Library of Congress a year ago began adding photographs with no known restrictions to a Flickr service called the Commons.

In May 2009, [[White House]] official photographer [[Pete Souza]] began using Flickr as a conduit for releasing White House photos. The photos were initially posted with a [[Creative Commons license|Creative Commons Attribution]] license requiring that the original photographers be credited. Flickr later created a new license which identified them as "[[Copyright status of works by the federal government of the United States|United States Government Work]]", which does not carry any copyright restrictions.<ref>{{cite journal |last=Singel |first=Ryan |url=https://www.wired.com/epicenter/2009/05/flickr-creates-new-license-for-white-house-photos/ |title=Flickr Creates New License for White House Photos |journal=[[Wired (magazine)#Website|Wired]] |date=May 11, 2009 |access-date=May 21, 2013 |archive-date=May 9, 2012 |archive-url=https://web.archive.org/web/20120509112353/http://www.wired.com/epicenter/2009/05/flickr-creates-new-license-for-white-house-photos |url-status=live }}</ref>

In March 2015, Flickr added the [[Public Domain Mark|Creative Commons Public Domain Mark]] and [[Creative Commons license#Zero / public domain|Creative Commons Zero]] (CC0) to its licensing options.<ref>{{Cite web|url=https://blog.flickr.net/en/2015/03/30/flickr-now-offers-public-domain-and-cc0-designations/|title=Flickr now offers Public Domain and CC0 designations|date=March 30, 2015|access-date=December 3, 2020|archive-date=December 1, 2020|archive-url=https://web.archive.org/web/20201201221807/https://blog.flickr.net/en/2015/03/30/flickr-now-offers-public-domain-and-cc0-designations/|url-status=live}}</ref> The Public Domain Mark is meant for images that are no longer protected by copyright. CC0 is used for works that are still protected by copyright or neighbouring rights, but where the rightsholders choose to waive all those rights.
