[Flash8] Need help with XML photogallery tutorial

Hi,

As part of my course at college I am designing a digital CV and I have got to the stage of presenting my work within the flash document. The XML with thumbnail photogallery tutorial on Kirupa was brilliantly written, but it does not tell me how to enlarge the file even more.

Basically I want users to click on the scrolling thumbnail, which enlarges it a bit and then have the option to click it again to see it even bigger either like a lightbox over most of the design or open in a pop up window. Is this possible in the Actionscript or XML file?

Tutorial I am using: http://www.kirupa.com/developer/mx2004/thumbnails.htm

All help is much appreciated!!!
