You can amend this letter to suit.
It has been bought to my attention, that you are/have been selling/showing as your own work and defacing items that have copyright images printed on them that belong to me.
Under international (Bern convention), UK (including the "Copyright, Designs and Patents Act 1998"), US, and other national laws, you are not permitted to copy any original work of art including photographs which are subject to copyright without the copyright holders consent.
Please note that prohibition from copying images includes using derived and modified versions of images, because the modification itself entails copying.
Please cease using any and all of my copyright images immediately, and desist from using them in the future.
I may have already given notice to [website management, ie:eBay] about your infringement, and reserve the right to do so in future.
If you are in any doubt about which image or images you have used, it follows that you must have used images from a variety of sources, in which case you almost certainly have infringed the copyrights of others. It is not my responsibility to identify each and every image to you, or to provide proof of my ownership of the rights to the images. However, if you insist on me providing to you with copies or the locations of each original image, I retain the right to charge you an administrative fee.
I request that the copyright images be removed from your listings within 24 hours of receipt of this notice, if they are to be seen after the 24 hours you will give me no choice but to take further action against you. This may incur considerable costs to yourself.
