Yeah idk about that part, I don’t have need for a screen reader yet. But I sure do appreciate contextual info. And it doesn’t have to be super detailed. “My cat, a brown tabby, naps on my couch” is fine for example, you don’t have to detail every bit of the image, just what someone needs to know.

"This is just a pic of something that happens in the story- it's just here for decoration"?
