Load individual .jpg from array

programming flash
1

Man, I could use some help here. Yeah, I did search for the answer. No luck. Anyway here I am asking for help.
I am using the code from “Photo Gallery Using XML and Flash”. I would like to add a number of buttons linked to the individual .jpgs so the viewer can load the pic directly. The catch is I would also like to use the neat funtions of the code below(loader, fade effect, and captions). How do I call these neat functions for use in my individually loaded .jpgs?

Any ideas or thought will be appreciated.

function loadXML(loaded) {
	if (loaded) {
		xmlNode = this.firstChild;
		image = [];
		description = [];
		total = xmlNode.childNodes.length;
		for (i=0; i<total; i++) {
			image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
			description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
		}
		firstImage();
	} else {
		content = "file not loaded!";
	}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("one.xml");
