Loading external swfs using XML

I have been using the flash photo gallery found in the tutorial section here. Its great and so user freindly when it comes to updating stuff via the XML. I really want something exactly the same as this but that loads in swfs instead of jpegs?! Is there a simple modification I can make to the code to get this to work. Ye4s tehre are other tutorials about loading in external flash but they are not as good and its not through an XML file. ANy help wpuld be fantastic as Im only a beginner on the XML front.

Heres the tutorial!!
