XML + thumbnail preloader

programming flash
1

Hey guys,

I’ve adapted the xml photogallery on this site to preload the image, but I would like to also be able to preload thumbnails (individually)

Here’s the code so far:

gallery=1

loadVariablesNum("http://www.substratemedia.com/IGPC/gallery_Display.php", 0, "POST");

myPhoto = new XML();
myPhoto.ignoreWhite = true;
myPhoto.onLoad = function(success) {
    //portfolioTag = this.firstChild;
    numimages = this.firstChild.childNodes.length;
    spacing = 85;
    for (i=0; i<numimages; i++) {
        this.picHolder = this.firstChild.childNodes*;
        this.thumbHolder = thumbnails.createEmptyMovieClip("thumbnail"+i, i);
        this.thumbHolder._x = i*spacing;
        if (i>=3) {
            this.thumbHolder._y= 60;
            this.thumbHolder._x= (i-3)*spacing;
        }
        if (i>=6) {
            this.thumbHolder._y=120;
            this.thumbHolder._x= (i-6)*spacing
        }
        this.thumbLoader = this.thumbHolder.createEmptyMovieClip("thumbnail_image", 0);
        this.thumbLoader.loadMovie(this.picHolder.attributes.thmb);
        this.thumbHolder.title = this.picHolder.attributes.title;
        this.thumbHolder.main = this.picHolder.attributes.main;
        this.thumbHolder.onRelease = function() {
            loader.loadMovie(this.main);
            this.onEnterFrame=function() {
                totalBytes = loader.getBytesTotal();
                bytesWritten = loader.getBytesLoaded();
                percent = bytesWritten/totalBytes *100
                galleryPreloader._visible = true
                galleryPreloader.bar._width= 1.88 *percent
                if (percent >99) {
                    galleryPreloader._visible=false
                }
                
            }
            title_txt.text = this.title;
        };
    }
};
myPhoto.load("xmlphoto.xml");

I can’t seem to be able to trace getBytesTotal() for any of the thumbnails. Any advise? I appreciate the time everyone
