Am I the only one not seeing the images from the site in Google Reader? There is a placeholder image that says something about phpThumb AntiOffSiteLinking...
So it seems something may have just been implemented to prevent hotlinking, but it is also preventing views from web-based feed readers. Admins, if this is the case, you may want to consider adding some exceptions to your .htaccess file for common readers (google, yahoo, netvibes, etc...)
