Help with adding objects to the current frame

1

Hello all, I am new with ActionScript but not entirely new to programming so I haven’t had many problems with it. However I am trying to make a slideshow like slide.com’s. I have 3 layers:
Actionscript
Preloader
Images

This is the ActionScript in the Images layer:


stop();
 
import flash.display.*;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.xml.*;
import flash.events.*;
 
function loadXML() {
    
    var uLoader:URLLoader = new URLLoader();
    var id:int = root.loaderInfo.parameters.id;
    uLoader.addEventListener(ProgressEvent.PROGRESS, onXMLProgress);
    uLoader.addEventListener(Event.COMPLETE, onXMLLoaded);
    uLoader.load(new URLRequest('images.xml'));
 
}
    
function onXMLProgress(event:ProgressEvent):void {
    
    trace('Loaded: ' + event.bytesLoaded, 'Total: ' + event.bytesTotal);
    
}
 
function onXMLLoaded(event:Event):void {
 
    gotoAndStop(2);
    var loader:URLLoader = URLLoader(event.target);
    var _xml:XML = new XML(loader.data);
    var images:XMLList = _xml..image;
    var x_position:int;
    var y_position:int;
    var w:int;
    var h:int;
    var i:int;
    var thumbnail:Loader;
    w = 1;
    h = 1;
    for each(var image:XML in images) {
        x_position = 75 * w;
        y_position = 20 + (85 * h) - 85;
        thumbnail = new Loader();
        thumbnail.load(new URLRequest(image.path.toString()));
        thumbnail.x = x_position;
        thumbnail.y = y_position;
        thumbnail.name = 'thumbnail_' + i;
        trace('title: ' + image.title.toString());
        trace('x: ' + x_position);
        trace('y: ' + y_position);
        w++;
        h++;
        i++;
        if (w % 6 == 0) {
            w = 0;
        }
        if (h % 4 == 0) {
            h = 0;
        }
    }
}
 
loadXML();

On the stage there is 20 pixels before the thumbnails are supposed to be layed out, so I have tried to accommodate this. So the objects I want to create are the thumbnails. My problem is they are not showing up, and I have a valid image URL in the XML. Can anyone tell me how I would fix this? How do I do this in AS3? Thank you for all the help.
