You can do an experiment. Go to the gallery area and find any photo. Then, click on the photo and then click "Tell a Friend" and put the guy's email in. See if he gets the photo recommendation. If he does, let us know and we'll look at the invoice tool to see what's happening.

Also, is the guy a member here? If so, what is his userame. His email address here my be out of date.
