A question about one of Kirupa's tutorial

Hi I just finish this wonderful tutorial here.
and here http://www.kirupa.com/developer/mx2004/xml_flash_photogallery.htm

I was wondering how to assign a url to each image, I like to use this as a news gallery vs. a photo gallery so I want a people to click on the images and go to their respective urls.

I know this is a simple thing to add but I have no clue where to begin. :stare:

Any suggestions / tips?
