"This image viewable only from CoasterBuzz.com"

Ok, I'm looking at a black square from CoasterBuzz.com. I can understand wanting to protect images from illegal use,but what gives?

Most likely, you're behind a paranoid firewall that doesn't pass through the "referrer" information. That information is used to determine if the image load came from Coasterbuzz, or from some other random website trying to leech off CB.

Jeff has an excellent description of how his anti-leeching filtering works here.

Here's more on how to fix it.
