My husband and I are having a bit of an ordeal with one of our "guests" that attended our wedding. Actually the guest was his brother's date. Anyway, she brought her digital camera and we were under the impression that she was just going to take some candid pictures just like most guests do during a wedding. Now, we have come across a Wedding Photography website that is hers, and she is using our photos as advertisement! We were never presented with a contract, and we never gave her permission to use our photos in this way. This makes me very upset. We weren't even aware that she had a wedding photography business. In fact, we didn't even know she was taking pictures until after the wedding! What should we do?
