I think you bring up a really good point about gifs, @silentdiscourse. And what if a gif-maker took a photo from somewhere online, without permission, made a gif and it went viral? Suddenly everyone is using it, and we might not realize that the original photo is unattributed.

I heard that the parents of this toddler were dismayed at first to realize their photo was being used by strangers all over the world, but are ok with it now.
