@box464 But it also occurred to me that I might be wrong about my assumptions. What if this person does have sight issues they're not comfortable sharing? What if they might want to share the image with a blind person, it would be nice if they could just copy the alt text? What if the image is confusing? Alt text might provide more context. Or help if the internet is too slow and the image takes a while to load.
@box464 I am not really disagreeing with you here, just thinking out loud. Let me give this a bit more thought.
