Micah, I appreciate the zeal with which you're coming up with creative images to complement the articles, so please don't take this the wrong way. But I talked with Matt last night, and we agreed that we aren't looking for "silly" pictures to highlight the articles.
The picture on "Genesis" is great. A picture of costumed Star Wars geeks next to "polygamy" would be... well, just not in keeping with the tone of the Wiki.
Don't get me wrong, we all appreciate a good joke, which is why when the Wiki first started, I added a picture of the Soup Nazi next to Ray Comfort, and I put a stub article for "Jesus" that said "Born of a virgin, miracles, rose from the dead, yada yada yada..."
But as the wiki evolved, we deleted those things. We're trying to present a site that's fun to read, but ultimately we also want it to contain serious presentations that challenge readers to think about the topics. Having a "punny" image at the top of the page would distract from the main points in the articles.
