And also: either you are already forgetting about image descriptions (because we don't tell you multiple times a day?) because there are so many pictures without or the feature is only working on a few select images. Guess it's not that though 
Yes I'm pissed, it's really not that hard, just inconvenient. So go and write image descriptions!
