I have lost contact info for some of my girlfriends. I want to find their real address names and where are they at the mic and telephones. How and what site to use to find my friends only by photos?

You don't. It can't be done. And if they really were friends and wanted to be friends, you wouldn't need to find them by photos.

There are sites that search by photo. In order to find the photo using any of those sites, the photo must first be in their database, and it has to be the exact photo you have. In other words, you'd have more luck finding a needle in a field of haystacks.

It's not possible.

Try Facebook, or Google. Search Facebook by their names, first and last, and Google too. You may get lucky.
