I just found holding_glasses, which seems to be the same thing, more or less. I think that'll probably be fine, even if she is holding them with her mouth. The only thing it really doesn't cover is if the glasses are lying on the table or something...
I also noticed that there aren't any whales in the picture. Should I add a "no_whales" tag? I think that'll probably be fine, even if it might be just as pointless as discussing what else the picture does _not_ show.
