ActionScript 2.0 :: Add Load Movie Between Xml Images?

I have gone through the xml slideshow tutorial and have built a simple xml slideshow. I am trying to add a transition between each of the images that looks like many bubbles adding to make an all white screen.i would like to insert something like this: container.loadMovie("bubbletransition.swf");the images transition every 3000 milliseconds or 6 seconds, can someone tell me where to add the code to add the swf at 5 seconds or around 2500 milliseconds.

here is my existing code:
stop();
var total;
