@CStamp @CatHat @RachelThornSub Honestly though, as someone born blind, it took me years to learn just how many of the images sighted people attach to things are "because the layout looks better with an image there" or "we need a thumbnail for the thing" or "everything else like this has an image so they all have to have one" or "I can post images so damn it I'm going to" or "boobs or blood so you'll click". From what I can tell, on most websites, only maybe ten percent of the images on a page need alt-text longer than a few words, because the person who added them is communicating nothing useful at all. On Mastodon, obviously, that's different, because you intentionally posted the image. But even here, ninety percent of images are posted to communicate "nature is pretty" or "my cat is cute". It's the other ten percent that need the long and thoughtful alt text.
