Got to looking at what was provided above, and well, for the most part the code is "right", but in trying to apply product image zoom (plugin available from cvhainb) doesn't appear that the javascript for that plugin is getting loaded, so the extra code doesn't seem to help. I'm working to see what it takes to get that javascript loaded, but atthe same time am I to assume that it is more desirable to just get the zoom to work that is part of IH4 instead? That's a different (yet somewhat similar) path/set of code.
