Mastodon users, new and old:
You can add a caption, or alt-text, to images you toot!
These captions make your toots more accessible, by giving people who can't see the image a description of what's in the image.
Just hover over the image over you attach it and type a description in the spot that says "Describe for the visually impaired" before you hit the TOOT! button.
Please also encourage Mastodon app authors to add caption functionality. And please boost. Thanks!
@Kit You mean captioning an image on mobile web?
I don't use it; I'm not sure how that would work. Can you tap the lower part of the image to add the caption?
