Just saw this article on CNET and thought maybe someone could use this.

I guess it would be for people who dont have photoshop? Anyway, it takes any image and gives it a reflection... pretty interesting stuff

That's pretty cool. The file is also pretty small so if you want to add a bunch of reflections it will probably create a smaller page to use the reflection.js script instead of adding to the image size. It's also less work.
