So I just had to deal with my first image hotlinker. The person was taking a lot of my images and posting them in forums.... and they met tubgirl. How do you deal with this problem?
You can use an htaccess file to prevent hotlinking. To find out how, go to google and search the term "htaccess hotlink protection". The files are very easy to build - take no special programming skill, and can be up and running in minutes. Bandwidth theft is a serious crime... htaccess is the solution. Good luck Zach - let us know how you fare.
