Bombcast episode images?

I'm attempting to learn how to integrate XML into Flash by making a Giant Bomb app. I've gotten most of the Bombcast data I need by referencing the page they have set up for the RSS feed. I'd like to be able to incorporate the 75x75 preview images that accompany each episode, but they aren't included as part of that feed. Is there another XML list online somewhere that includes all of those images? I didn't see anything in the API documentation that pertained to the Bombcast.
