@bright_helpings YES. 100%. It's not just for blind critters.
Sometimes the image won't load. Sometimes we just have no idea what the absolute fuck we're supposed to be looking at. (Like, "what's important in this photo, why are you showing it to me?" type thing.)
@bright_helpings ...although I don't really get the "or people who otherwise don't feel that image descriptions are for them" thing? *headtilt* 'Cause image descriptions are definitely for us too.
