After some thought, I figured out a way to do it (without javascript), but not exactly the way your CSS code was working.

This is the template, which includes the necessary CSS in the documentation.

Basically, instead of defining the image to be used as a CSS background that changes, this template places two images on top of each other—One visible and one invisible. When you hover the mouse over the visible image, the invisible one appears on top of it.

...oh, and the hover image loads the first time you hover to display it, so it may be slow (especially for large images) the first time.
