Rocky,

I had a similar experience with another on-line seller using photographs I took of a product for our museum's gift shop catalog on his web site. Before I contacted them I did some research on the company (for instance, looking at X Marks for customer feedback), and in this case all of the feedback on X Marks for them was very good. Everyone had great things to say about the guy who ran the company and his customer service.

Since I actually knew who the guy was and how to contact him, I did so directly. I pretty much told him that those were my photographs, they were taken specifically for the museum's gift shop, and to remove them from his web site ASAP. He tried to backpedal at first (he claimed the images were supplied to him from the manufacturers as stock images), but once he figured out I was serious he took down the images almost immediately.

Sometimes directly contacting the person is best. In this case it's impossible because it's an ebay seller and you don't know who they are. So, I'd contact ebay directly and see if you can get satisfaction that way.

Good luck!
