Will eBay automatically consider my photos for inclusion in the eBay product catalog?
Yes, eBay will begin to select photos from sellers' listings for inclusion in the eBay product catalog starting on September 1. If you don't want your photos used, you can opt out at any time. If you opt out by August 31, 2009 at 23:59:59 PT, none of your photos will be considered for inclusion in the catalog unless you opt back in at a later time. If you opt out after August 31, 2009 23:59:59 PT, any photos we select for inclusion in the catalog prior to your opt-out may continue to be used in the catalog.
