Rotate your images with a nasty porn pic or something like that.

I have done this in the past when people were stealing images/bandwidth.

The first Empeg auction layout I had was "borrowed" by a few sellers. I subsequently changed to a layout that only Netscape would submit to eBay. This seemed to fix the problem. For some reason eBay's programs do not like it when IE submits too many lines of html code or something like that. Look on their site, they specify to use Nutscrap if you have any problems with submitting auction html code...
