Another reason to add #AltText to your photos, basically, anywhere, is that, yes, there are sighted people that disable all images in their browsers because it's faster to browse. #Internet#Tech#Technology#Accessibility
I think my case is far more common: I, a sighted person, look at the image, and I don't know what I'm looking at.
Sometimes I think I know what I'm looking at, but then the alt text tells me the intent of the person who posted is not at all what I thought.
E.g. I think I see a beautiful photo of a sunset behind mountains, but the alt text says: "wildfires are turning the afternoon sun red". Then I think: Good thing there was #AltText.
@potungthul@weirdwriter Hmm, actually, I think this is a place for a photo caption, as text on the web page, reading "wildfires are turning the afternoon sun red" while the alt text reads "red sun behind mountains". Alt text is meant to convey what a sighted person would see. Meaning belongs as text on the page.
Agreed that that is the role of captions. Still, often #AltText will reveal the intention behind the picture, something the writer had assumed was obvious, but not to me.
Also, often it is hard to get alt text to describe every single aspect of the picture. Knowing what the writer did describe lets me know where to focus my attention.
E.g. "class photo. Everybody is frowning" is very different from "class photo. Everybody is wearing red", even if it's the same photo.
