Script Summary: Automatically turns all links to images into inlined images.
This intentionally doesn't transform images linked in signatures. It doesn't always work in links that have lots of images in the description. If a linked image is on a site that doesn't allow hotlinking, you'll still get the "don't link my images" image instead of the actual image.
8/3/09 Added compatibility for internal image linking, improved code
3/2/09 Updated for domain change
