An interesting issue on the Github repo of Mastodon : github.com/mastodon/mastodon/p What should be the size limit for an alt text on an image?
The current limit of 1500 chars is fine by me, as an alternative text should stay short. If a long description is needed, it can always been done in the toot or a thread of toots.
Isn't there a risk of encouraging very long alt texts by increasing this limit?
What do you think?

Fixes #22096. An image is worth a thousand words, isn't it? And so, I've decided to test this, by generating 1000 words of text with a generator. And, wouldn't you know it, it turns out...

RE: front-end.social/@AlainVagner/

This has come up before. Screen readers do not have a limit. Long-desc is no longer supported. However for much longer alt text, it probably makes more sense to put in an aria-described by pointing to a paragraph or page describing the content.

I don't think that a 1500 character limit is unreasonable. Most folks barely do 20.

But then maybe maybe NASA won't like it npr.org/2022/07/22/1112878868/
