Hi Mark,
Thanks a lot for your reply. I would like to basically copy exactly how the newer versions of x-cart have it set up with the little question mark icon to click on and the images already in place on the pop-up window that they have. Here is the link to the pop-up on their demo.

Is there a way that I can copy the exact look of the new one into my 3.5.8 cart? Thanks again!
