How can I find someone by just having a photo of them?

Where did you get the photo from?

Well it'sike this I met someone on a dating site on the web, they sent me pixs of them and I was led to believe that was them. They had told me they were photos where they had done some modeling work. So for six weeks I talked to this person and we were getting ready to meet for the frist time. Well to make a long story short a third party e-mailed me and told me it was all a lie! They say the photos came from the web and mags. And I just wanted to find out who the person was in the photo.

It could be a pic of anybody he could have gotten it from a myspace profile.
Most likely like looking for a needle in a barn full of hay.
Unless it was some professional, at least semi famous, models pic you most likely never will track down who it is.

OK thanks!
