Load external swfs than images?

Found this tutorial here on Kirupa

http://www.kirupa.com/developer/mx2004/xml_flash_photogallery.htm

is there any way that instead of it loading images, it’ll load an external swf instead?
I also, want to keep the navigation to just “next” and “previous”

If so, can I be pointed to a tutorial that will teach this?

Thanks
