All photos on Ebay are the property of Ebay and not the person who posted it. Ebay says it's okay to use their photos.
False.
By uploading images to eBay you are granting eBay a non-exclusive license to use those images, but ownership remains with the seller.
Note that this grant's *eBay* said license, not other sellers.
There is a mechanism to report other sellers using your intellectual property. Now whether eBay does anything to enforce this is up for debate...
