This great shot of a Macaque Nigra in Indonesia is — according to Wikipedia at least — in the public domain. That’s because although it came from a photoshoot by David Slater, the picture was actually taken by the monkey itself after getting its hands on the camera.  Wikipedia says that means the picture can’t be copyrighted as it’s not the work of a human.
