Who's the guy on the left in this picture?

There is really no way to ID a photo of a person. Why would you doubt he would send a real photo.

There is no picture.

There's no picture but let's assume there was....how would you expect us to know who it is? We are not magic and there are billions of people in the world.

Do you have a reason to doubt this person?

Ask him who this other guy is.
