If you right click on an image in firefox, you can block images from that site. Click tools > options then click the Web Features button and next to load images from site, click the exceptions button. Highlight ebay if it is in there, and click remove site.

I did not know if this was also happening in IE, from what I got it was just Firefox.

Hope that helps a little bit.

And yes, quit using IE. Its a horrible mess, and service pack 2 is great, minus the fact it screws with most people's IE browsers; and other firewall/networking settings
