@Alt Text Hall of Fame "People wondering WTF they're looking at" need an explanation. But: Explanations do not go into the alt-text! Ever! That's because not everyone can access alt-text, just like not everyone can see the image in an image post. And yes, this may be due to a physical disability. Any information that's only in the alt-text, but neither in the post text nor in the image itself, is inaccessible and therefore permanently lost to these people. Explanations always go into the post text body where everyone can access them! Money quote-posts from someone who actually does have a physical disability that keeps her from accessing alt-texts: Deborah wrote the following post Mon, 10 Jul 2023 17:56:06 +0200 @jupiter_rowland “Done right also means accessibility for people who might not know much about your image's subject matter either.” The person who posted this is simply flat out incorrect. Alt text is INACCESSIBLE to many disabled people. If the extra text is important, it needs to be in visible text. Deborah wrote the following post Mon, 10 Jul 2023 23:30:45 +0200 @jupiter_rowland I have a disability that prevents me from seeing alt text, because on almost all platforms, seeing the alt requires having a screenreader or working hands. If you post a picture, is there info that you want somebody who CAN see the picture but DOESN’T have working hands to know? Write that in visible text. If you put that in the alt, you are explicitly excluding people like me. But you don’t have to overthink it. The description of the image itself is a simple concept.

    @jupiter_rowland it's not always obvious what it's a photo of just due to framing or angle. usually the alt text will help with this in the way it describes the thing the poster wanted us to take away from it. that's still basic alt text info and not extraneous explanation i.e. what is this a picture of? i can't really tell what the scale of this object is alt text: this is a can opener

    @jupiter_rowland In that case, wouldn't it be better to have an option in the client to display the alt text below each piece of media without having to click anything? Because sometimes we don't even have enough space to properly explain the media in the post itself due to the 500-character limit. So I guess we'd have to make a thread? Does that also mean that we should only add one image per post, since some people can't click to expand it?
