I know that people ask this question all the time, but I've not found a tutorial that works yet, I've looked just about everywhere.

I'm trying to preload 4 dynamic jpgs. I put this script on the key frame that has the host_mc on it and the loadMovie action too...I don't think its working...is there a more effective way to do this? I found this script in a tutorial on this site, if anyone wants to look at it:
http://www.flashguru.co.uk/000044.php

code:
this.loadMovie("homepage_clear.jpg");

//check the download status of the external

//movie once every frame

this.onEnterFrame = function() {

	//trace the percentage of the movie that has loaded

	percent = (this.homebackg_mc.background2_mc.host2_mc.getByte  sLoaded()/this.holder.getBytesTotal())*100;

	if (!isNan(percent)) {

		trace(percent+"% loaded");

	} else {

		trace("0% loaded");

	}

	if (percent == 100) {

		delete this.onEnterFrame;

	}

};
