I agree with this post. There’s nothing that bothers me more than hearing, “Picture of the event flyer.” or something like that.

just fyi summarising text in an image instead of pasting it into the alt text field is ableist too

the point is to know what the image says and make your own judgements about it rather than just read a summary from someone else

for some cases, summarising is unavoidable (“graph trending downwards”) but specifically for text, just use the exact text please. and if you use OCR, double-check the output and fix any obvious mistakes instead of just assuming it’s flawless

obvious exceptions apply for text that cannot simply be copy-pasted, where OCR is unavailable, or the author is low-energy, etc., but most of the time it’s just someone taking a screenshot and not directly copying the text into the alt when they have it
