XML help with adding categories to gallery with thumbnails and larger pictures

Hi, I was looking at http://www.kirupa.com/developer/mx2004/thumbnails.htm tutorial, This tutorial Almost has exactly what I want.

But being new to XML and the action script associated with it, I’m a bit lost when it comes to adding new things. Basically i want to have Album categories the same way the thumbnails work so their is a mask limiting 4 categories on screen and when you click < or > arrows next to the categories it shows the next 4 categories that you would be able to choose from.

Then I would want it to load whatever category you selected into the thumbnails and the larger pic.

Does anyone know how to do this ? Or if their is another tutorial that would show me how to add categories into something like a gallery with thumbnails?

Apologies for being stupid and the poor grammar :rabbit:
I’ve been searching everywhere to find out how i can add in some categories and still have it linked to the thumbnail scroller and larger images, but i haven’t found any luck at all :puzzled: I just want it so you could add in as many thumbs and categories as you wanted and have those masked and scrollable rather then a dropdown.

I paid for some silly pdfs to explain it better to me but they did it in a way that I didn’t like and turned out just to be a waste of money. Learnt my lesson and signed up here to ask the pros! Hope you can help me out. I want to create something that can be updated from just an xml file.

I also Added a quick jpg to kind of illustrate what i want to have happen :confused:

Any information or direction you can provide is highly appreciated.
