Is there an algorithm that determines the photo on area pages?

I'm curious how the database selects the photo for the main area pages? Is it the photo with the most "great" votes? Is it the first photo posted to the area? Is it determined by the person who submitted the area?

I think the first pic posted is THE pic. The page author or area admin has the ability to change the photo at their discretion, but I'd guess most area pages have not been edited in this manner.
