I put a bunch of pictures on Riya in the past week or so. Riya is different because it identifies faces. Then, you tell it who the faces are, and it tries to find more faces in your pictures and identify them automatically. Then, it gives you a chance to tell it whether it was right or not. That way, you can categorize your pictures. I found pictures of people I didn't even know I have. Go ahead and go to www.riya.com and search for your name to see if I have any pictures of you.
