Lorrie, the link below describes a way to disable the 'right click' feature on your listings so that the page and images cannot easilly be copied.

It contains the code that you have permission to copy and use. Although it may not be completely foolproof it will slow them down. If they're too lazy to write their own ad and take their own photos then they're probably too lazy to work around this fix. The message displayed upon a right click can be customized by you by changing the appropriate line in the code. {found by a Google search for 'disable right click}

hope this helps reduce the frustration...
