I read this post over a month ago, and knew it would come in handy sooner or later. Today it did. Before, all of our rewriting was from one folder deep to one folder deep. But today, we added a rewrite from two folders deep to one folder deep, and our images were broken.

So I dug up Scott's post, and he saved the day. And it didn't cost me $75! Actually, that's twice now. His original MSDN article is what I used to do our rewriting (well, sort of).
