In a couple of different places on Mastodon this week I’ve seen people saying something to the effect of “what does visible alt text matter, it’s for screen readers.”

Here are just a few scenarios why people might want to view alt text visually:

1. “I made the post and I want to double check the alt text I wrote.”
2. “I did not make the post but I want to learn how other people write alt text so I can write better descriptions.”
3. “I’m having trouble making sense of the image but I think a written description would help.”
4. “My vision is enough to read text at my preferred font size but not in a tiny screenshot with jpeg compression.”
5. “This is what works best for me because of reasons I don’t want to get into.”

Accessibility is for everyone. Try not to make assumptions.

@arjache I get censory/light & color overloaded so I often look at alt-text when I'm having a flare in my osteoarthritis pain and thusly use those to help me focus better on the image components, as an option not mentioned above. And there are definitely others still. Alt-text being that important & widely used.
