Editing Incubator escapee wiki:Extended image syntax (section)

===Alt text and caption===
Zero or more of these options may be specified to control the ''alt text'', ''link title'', and ''caption'' for the image. Captions may contain embedded wiki markup, such as links or formatting. See [[Wikipedia:Captions]] for discussion of appropriate caption text. See [[Wikipedia:Alternative text for images]] for discussion of appropriate alt text. Internet Explorer displays the link title as a tooltip but other browsers may not.{{Update inline|date=June 2024|reason=Internet Explorer is obsolete.}}

Hint: to force the caption to be written (underneath the picture) and not just appear as "hover text" even when you wish to resize the image, specify "<code>thumb</code>". If you specify "<code>frame</code>" the caption does appear but any resizing (such as "<code>125px</code>") is ignored.

; <code>alt=</code>''Alt'': Use '''''Alt''''' as the alt text for the image.
; ''Caption'': (the last option that is not recognised as some other part of the image syntax): How this text is used depends on the image type. When the type has a visible caption ("<code>thumbnail</code>", "<code>thumb</code>", "<code>frame</code>" or "<code>framed</code>") then this text appears as a caption below the image. Otherwise, (if the image type is unspecified or is "<code>frameless</code>"), this text is used for the link title provided the link has not been suppressed with "<code>|link=</code>", and also for the alt text provided an explicit <code>alt=</code>'''''Alt''''' has not been supplied.

The actual alt text for the displayed image will be one of the following, in order of preference:
# The explicitly requested '''''Alt''''', if any;
# The explicitly requested '''''Caption''''', if the image type has no visible caption;
# The empty string, if there is an explicitly requested '''''Caption''''' and the image type has a visible caption.
# The image file name if there is no explicitly requested '''''Alt''''' or '''''Caption'''''. This is never a satisfactory option.

It is possible to specify the link title text only for images with no visible caption (as described above). However, as not all browsers display this text, and it is ignored by screen readers, there is little point.

'''Note:''' <code>alt</code> is supported only for images. Audio and video files should use [[Wikipedia:Manual_of_Style/Accessibility#Video|timed text]].
