Oh, oops! I'm sorry. I completely misunderstood. That's an even tougher question, then. Hm. I'm not sure if this is in Illustrator or Freehand, but there's an "envelope" tool that allows you to warp images to a particular shape. And in Photoshop, I would use Polar Coordinates to do what you want to do. I'm attaching an image to show the before and after using that tool.
