MX 2004: "gallery that loads all images at once" question

programming flash
1

I got this code from Scotty and it works great except that the preloader bar
is initially full instead of empty when the images are starting to load. Is there a way to fix this? Thanks.



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;
		}
		id = setInterval(preloadPic, 100);
	} else {
		content = "file not loaded!";
	}
}
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("images.xml");
var loadTot = 0;
var k = 0;
// ///////////////////////////////////
function preloadPic() {
	clearInterval(id);
	var con = picture.duplicateMovieClip("con"+k, 9984+k);
	con.loadMovie(image[k]);
	var temp = _root.createEmptyMovieClip("temp"+k, 99+k);
	temp.onEnterFrame = function() {
		var total = con.getBytesTotal();
		var loaded = con.getBytesLoaded();
		percent = Math.round((loaded/total*100)/image.length);
		preloader.preload_bar._xscale = loadTot+percent;
		info.text = "Loading picture "+k+" of "+image.length+" total";
		if (loaded == total && total>4) {
			con._visible = 0;
			nextPic();
			loadTot += percent;
			delete this.onEnterFrame;
		}
	};
}
function nextPic() {
	if (k<image.length-1) {
		k++;
		preloadPic();
	} else {
		firstImage();
		trace("hit");
	}
}
