Did Wikipedia get permission from the monkey to post the photo? Clearly they didn't think this through. In cases like this there should be implied copyright holder. Let's say I'm on vacation with a friend. I hand a stranger my camera to take a picture of us. Does that mean I can't post the picture on my facebook page without officially assigning copyright to myself? Of course not.
