Displaying image in Flash photo gallery

Hi, i’m been following this tutorial http://www.kirupa.com/developer/mx2004/xml_flash_photogallery9.htm to make a XML based photo gallery. Now i would like to add a feature which is to display the picture in full size. I tried using the get URL function to pull out a new page but i need to put a different link for each different picture. How can i do so?

I also wonder in some portfolio, i saw some photogallery which when the picture is clicked, the picture enlarges within the flash window itself. How can I do so?
