Nice project. A couple things I noticed: You're leaking emails and IP addresses of commenters in your source code. There are plenty of dead pages[1] in the index which you could redirect to the home page or just disallow Google to index either via robots.txt or Google Webmaster Tools.

Edit: Skimming through the site I couldn't actually find a single affiliate link from the image labels.
