http://upload.wikimedia.org/wikipedia/commons/5/52/Macaca_nigra_self-portrait.jpg?downloadLinky? I don't see that on the two images at: http://en.wikipedia.org/wiki/Celebes_crested_macaque#Copyright_test_case
That copyright tag would help the photographer's case, methinks.
I don't think Wikipedia's argument (that the monkey took the shot, ergo, cannot be copyrighted) will hold water either. Most folks would agree that the photographer owns the content on their camera(s).
Should be fun watching this play out.
