Richard Davey has updated his Easy Reflections PHP class according to a new post today:

I have updated my Easy Reflections code and released v2. Thanks to feedback and some code from Monte Ohrt (co-developer of Smarty) he added in cache support and fixed a banding issue with the alpha levels. It all works really nicely now - and the new version, with the new docs are available at http://reflection.corephp.co.uk.

The script takes any image (jpeg/png) and makes a reflection for it (he gives the album cover reflection in Apple's iTunes as an example). Configuration of the reflection is available including intensity, background, and height. Check out the galleries on motortopia.com for an example of it in action.
