Why have pictures of ourselves? Anyone could get a picture off google and claim it is them, and then it would be put in the mosaic. Also, it would just be better if people found a really funny picture, but appropriate, and it would be easier to find pictures. I know this sounds stupid, but I would rather want to see a mosaic of a bunch of funny picture, photoshoped or not, than a bunch of people I will never see in real life.
