Zoom in/out with multiple images?

I'm using the following script:

It's really great, but I'm wondering if there's a way to zoom in/out multiple images at once, preferably while laying on top of each other in div tags. My attempts to fiddle with the code aren't getting me anywhere -- any suggestions?
