Editing Digital image (section)

==Image viewing==

Image viewer software displayed on images. [[Web browser]]s can display standard internet images formats including [[JPEG]], [[Graphics Interchange Format|GIF]] and [[Portable Network Graphics|PNG]]. Some can show [[Scalable Vector Graphics|SVG]] format which is a standard [[W3C]] format. In the past, when the Internet was still slow, it was common to provide "preview" images that would load and appear on the website before being replaced by the main image (to give at preliminary impression). Now Internet is fast enough and this preview image is seldom used.

Some scientific images can be very large (for instance, the 46 gigapixel size image of the [[Milky Way]], about 194 Gb in size).<ref>{{cite web|url=https://www.techradar.com/news/world-of-tech/this-is-the-milky-way-in-46-billion-pixels-1307463|title=This 46-Gigapixel photo of the Milky Way will blow your mind|date=23 October 2015|access-date=5 July 2018|archive-date=5 July 2018|archive-url=https://web.archive.org/web/20180705233640/https://www.techradar.com/news/world-of-tech/this-is-the-milky-way-in-46-billion-pixels-1307463|url-status=live}}</ref> Such images are difficult to download and are usually browsed online through more complex [[web interfaces]].

Some viewers offer a [[slideshow]] utility to display a sequence of images.
