Thanks for the help.
I changed out the .htaccess file I was using for the shorter, revised one you did. I cleared my cache, deleted temp. internet files and restarted my computer and I still see the images being hot linked.
Does anyone else see the images or are they broken?
What does "send an empty referrer" mean? Does that mean I just go straight to the url without clicking on a link? I'm so technically challenged!
