Problème redimensionnement image apres chargement externe

var conteneurImage:Loader = new Loader(); 
 
var image:URLRequest = new URLRequest("av1.png"); 

conteneurImage.load(image); 

this.addChild(conteneurImage);

conteneurImage.width = 50;

	function loadImage(path:String):Loader
	{
		var request:URLRequest = new URLRequest(path);
		var loader:Loader = new Loader();
		loader.load(request);
		loader.contentLoaderInfo.addEventListener( Event.INIT , loaded)
		return loader;
	};
	
	var image = new Array();
	
	for(i=1;i<4;i++)
	{	
		image[i] = loadImage("av"+i+".png");	
	}

	function loaded(event:Event):void 
	{
		var targetLoader:Loader = Loader(event.target.loader);
		targetLoader.width = 60;
		targetLoader.scaleY = targetLoader.scaleX;
	}
	
	this.addChild(image[1]);

	var image = new Array();
	
	for(i=1;i<4;i++)
	{	
		var requete:URLRequest = new URLRequest("av"+i+".png");
		image[i] = new Loader();
		image[i].load(requete);
		image[i].contentLoaderInfo.addEventListener( Event.INIT , ChargementTermine)
		
	function ChargementTermine(event:Event):void 
	{
		image[i] = Loader(event.target.loader);
		image[i].width = 60;
		image[i].scaleY = image[i].scaleX;
	}	
	}
	
	this.addChild(image[1]); // image affichée en 60px de large
	
	// comment faire pour l'afficher en 100px de large par la suite?
