Art project

Aaalso, it's about an Internet project. I'm creating a home page, which deals with the theme of "identity hopping" on the Internet. save the date templates
The Internet is so anonymous and no one can control whether the identity for which it purports to be, is the reality.

On this website, I'll then create profiles of people that do not exist in reality. I need photos of people I don't know ("from the Internet for the Internet") for the said fact sheet. Everything else, name or hobbies, residence etc. is virtually invented and not there.
The user can then log on a profile, and for the time that he is on the website, to impersonate this fictitious. There should be a forum and an online diary.
For which profiles he decides or how often he changes this profile or identity is any user, then left. He can also decide, how much he reveals his own identity, or whether he considers this fact sheet identity as a kind of role-playing...

To violate any copyright laws, I need the person shown on the photo of course OK.
I've found that it is very difficult to get such photos. Can someone help me here maybe? Or does anyone know of someone who could help me? This would be super - the ran out of time namely me...
Thank you very much for your help! Tazzy82
