Lovely.. the guy in that auction stole my picture of my Empeg in my Miata...

If you are unhappy about his usage of your photograph without your permission, you can ask him to take it down. Note that ebay's own guidelines are very specific on this point and require that the users supply their own images. If he does not comply, you can notify ebay and have them do something about it.

Here is a thread about this very topic.
