Has anyone had any joy with this ?trying to find someone with just a photo ?

I don't know what you mean by "joy" (unless it's a question of language) but, yes, I've located people from photos.

You need expensive software AND a reason to do it.

Sorry I meant success with just a photo.What type of software do you mean ?

You buy computer software which is about $500. I've seen various programs demonstrated - some are better than others.

Ok thanks for that .

Just out of curiosity - what are the circumstances behind trying to locate this person?

Also your age.
