eBay Guideline:
The fact that material is posted on the Internet does not mean it is in the "public domain" or otherwise free to be taken, copied or used by others. Creators of Internet content probably have copyright, trademark and other rights in the material they create. Copying, modifying and possibly linking to content created by others could expose you to legal liability.
eBay Guideline:
Copying is not permitted: when you prepare your listings you generally should use only material (text, photographs, etc.) and trademarks/names that you created or own yourself or licensed from the owners.
