Xml photo gallery

First off let me say that this is a great and handy tutorial. Super useful and easy to follow. Thanks for the attention to detail.

Here is my question, is it possible to load the images xml files in the background? That is to say, while I am looking at the first images is it possible to keep loading the images later in the list (rather than waiting for me get there to load them).

If its possible, could somebody let me know how. Thanks in advance.

This is the code that I am working with:


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("images.xml");

listen.onKeyDown = function() {

	} else if (Key.getCode() == Key.RIGHT) {

	}
};
Key.addListener(listen);
previous_btn.onRelease = function() {
	prevImage();
};
next_btn.onRelease = function() {
	nextImage();
};

p = 0;
this.onEnterFrame = function() {

	loaded = picture.getBytesLoaded();
	preloader._visible = true;
	if (loaded != filesize) {
		preloader.preload_bar._xscale = 100*loaded/filesize;
	} else {
		preloader._visible = false;
		if (picture._alpha<100) {
			picture._alpha += 10;
		}
	}
};
function nextImage() {
	if (p<(total-1)) {
		p++;
		if (loaded == filesize) {
			picture._alpha = 0;
			picture.loadMovie(image[p], 1);
			desc_txt.text = description[p].toUpperCase();
			picture_num();
		}
	}
}
function prevImage() {
	if (p>0) {
		p--;
		picture._alpha = 0;
		picture.loadMovie(image[p], 1);
		desc_txt.text = description[p].toUpperCase();
		picture_num();
	}
}
function firstImage() {
	if (loaded == filesize) {
		picture._alpha = 0;
		picture.loadMovie(image[0], 1);
		desc_txt.text = description[0].toUpperCase();
		picture_num();
	}
}
function picture_num() {
	current_pos = p+1;
	pos_txt.text = current_pos+" / "+total;
