How can I find an original facebook picture using a downloaded picture?

[$$Rogerf95$$]

A friend downloaded a picture from facebook and sent it to me and I looked at the details of them and each say Facebook$IMG_(followed by a long number) I was wondering if I could use this to find the source if so how? he doesn't remember where he found it

I tried http://Facebook.com/(the number) but it didnt work

there is no way to do that - facebook doesnt use the same antiquated system that myspace does
