Load swfs with button and time interval

I am building a simple rotating header/banner section by loading external swfs. I found this tutorial very helpful :

I am trying to integrate this with a time interval to automatically switch to the next swf.
basically I need to have the buttons to load each swf, but add a play/pause function, previous, and next. Is there a tutorial out there that anyone knows about ? Any help would be greatly appreciated. Thanks !
