In the front end it doesn't do a thing. A new window opens when an image is enlarged, so no Zen light box is openend.
Not really sure where to tell you to start.
If it's not working on the front end OR the back end, I have to assume the files are not installed correctly. Did you rename all of the 'your_template' folders to match the andover directory name?
