Although this was some years ago now and eBay has changed quite a bit since then, when it happened to me I contacted eBay Customer Services and explained what had happened, pointing out that I had taken those photos and used them on my own listing, making sure that I gave the eBay representative my own advert's item listing number, then I gave the eBay representative the item listing number of the advert that was using my own photos without my consent. I stated that the seller had not even asked me if he could use my images and therefore stated that I wanted my photos removed from the other listing. The eBay representative who I was speaking to was actually very helpful and said that she would ensure that the matter would be dealt with. Within twenty-four hours eBay had removed the listing that I had reported from the site.
Should you wish to contact eBay and report the matter to them the best option would be to use the option to have somebody call you. eBay recently moved the location of this option on the site - at the time of typing this response you can locate it by clicking on the Policies link at the bottom of this page. When the Policies page loads up scroll right down to the bottom of the page and click on the mobile phone icon on the left hand side of the screen next to the words "Have Us Call You." An eBay representative will call you back shortly afterwards, so if you explain the situation to the eBay representative and provide him or her with the listiing number from your own advert, as well as that of the listing by the seller who is using your photographs without your consent then eBay may well remove the seller's listing as they did in my case.
