Just looked at the source of the page, noticed the link to the image is:
attachment.php?attachmentid=&d=&stc=1
Between the attachmentid= and the & should be the id number of the attachment (Example: attachment.php?attachmentid=1875&d=1257193874&stc=1&thumb=1) . Seems it's missing. Not sure why, but would explain why you're not getting the image.
Edit: hmmm missing the bit in Blue as well.
