Wonder if anyone has any advise. I'm selling on ebay and some other seller is using one of my images. Problem is the seller is selling the same product I am and using a slightly different picture then the one I'm using in my listing. Because of this ebay won't take the other sellers listing down, since it's not the same and I can't prove the image is mine. They lifted it from an educational website that I let use it prior to thinking I would ever use it to sell with. The image was never formally registered or anything. Is there a way to prove to ebay that the picture is mine? It's pretty obviously since its so close to my image, but that's ebay. Thanks in advance for any info.
