I found the code in the CSS file included, and copied that to my template Stylesheet. I put it at the end, but I didn't think that would matter.
It's the Java Script file that is causing the problem. If I rename it I don't get the pop up in the header section. I don't get a pop up at all, and that's O.K. , but with that file renamed I don't get an enlarged image when I click on the product image file. I'm using the Gloss_Blue template, and I think there is something in there telling the java script to show in the header section.
