Among friends, I created trivia contests in a forum. I put in images, and asked who, what, where etc. about the picture as the question. The big reason I did this is that if I'd asked a text question, anyone could just Google it.
Now I guess I'll have to urge folks even more not to cheat. Sure this ability was there by other means already, but Google is mainstream.
I'd like to try out various image manipulation to see how far an image can be altered before it no longer finds a match equal to the original. Oh, bother. Is it going to just become "who can tell what this image used to be before I digitized (granulated) it?"
