This letter arrived yesterday from the USA, ( see images ) I am a bit worried as I sent the
photo "let it flow" (see Champagne shot ) to the Amateur Photography
competition. And I can't work out how this company got hold of the photo!
I can't work out if it is a scam or not and if I should respond to it?

They have put the photo on their website ( picture.com ) I had to search under my name to find it, I was wandering if anybody has heard of this company?
