What version of ShopSite are you using?
Is it a Pro, Manager or Starter level store?
What theme (template) are you using? Some of the older ones may not have this functionality built in but the newer ones do. The functionality was added in ShopSite 10sp1 so themes newer than that should have the functionality (See http://www.shopsite.com/templates/cookbook/builtintemplates.shtml to find out when different themes were added to ShopSite.)
You have to have multiple Moreinfo Images for the function to work since it needs more than one image enabled. Settings for image are found on the Product > Edit Product Info screen and settings for the display of the more info image are found on Preferences > More Info Pages near the bottom of the screen in the Image Roll Over section.
