A post that has additional commentary in the "alt" text of the image.
The alt text is an additional written description of the image, supported by some sites. It's usually seen by clicking an "ALT" button in the lower left corner of the image. It's intended to provide a written description of the image for blind users, but normally it's also used by artists as extra commentary (in a similar vein to the title attribute of the <img> element). It's called "alt text" because in HTML, the text is stored in the alt attribute of the <img> element, like this:
Alt text is currently supported by Twitter, Tumblr, and Bluesky. The alt text should be placed in the artist's commentary if it isn't automatically retrieved from the source.
Be sure to add the commentary request tag if the text needs to be translated. If the source has multiple images with alt text attached to them, do not feature every image's alt text in the commentary of one image, unless necessary (ex. image #2's alt text builds off of image #1's alt text). Only include the alt text of the given image.
