I'm using 1.3.7 zen-cart and Classic contemporary green template. When I click on the thumbnail image to see the larger image, the larger image is not centered.

I have a test example here.

I'm on a Mac. The problem occurs on Firefox and Safari. I don't know if it centers correctly on Windows.

My image is 640x480 pixels.

Other sites I've done with zen-cart do not have this problem. Any suggestions?
