quando clicar na imagem ir para uma pagina tentei o geturl mas nao foi

// importando a classe de efeito do flash
import caurina.transitions.Tweener;

// tempo para a troca de banner
const TIMER_DELAY:int = 1000;
// tempo fade

const FADE_TIME:int =	2;

var currentContainer:Sprite;
var intCurrentSlide:int = -1;
var intSlideCount:int;
var slideTimer:Timer;
var sprContainer1:Sprite;
var sprContainer2:Sprite;
var slideLoader:Loader;
var strXMLPath:String = "banner.xml";
var xmlLoader:URLLoader;
var xmlSlideshow:XML;

function init():void {
	xmlLoader = new URLLoader();
	xmlLoader.addEventListener(Event.COMPLETE, onXMLLoadComplete);
	xmlLoader.load(new URLRequest(strXMLPath));

	slideTimer = new Timer(TIMER_DELAY);

	slideTimer.addEventListener(TimerEvent.TIMER, switchSlide);

	sprContainer1 = new Sprite();
	sprContainer2 = new Sprite();
	mcSlideHolder.addChild(sprContainer1);
	mcSlideHolder.addChild(sprContainer2);

	currentContainer = sprContainer2;

}

function onXMLLoadComplete(e:Event):void {
	xmlSlideshow = new XML(e.target.data);
	intSlideCount = xmlSlideshow..image.length();
	switchSlide(null);
}

function fadeSlideIn(e:Event):void {
	currentContainer.addChild(slideLoader.content);
	mcInfo.lbl_loading.text = "";
	Tweener.addTween(currentContainer, {alpha:1, time:FADE_TIME, onComplete:function() { slideTimer.start(); }});
}

function switchSlide(e:Event):void {
	if(slideTimer.running)
 slideTimer.stop();

	if(intCurrentSlide + 1 < intSlideCount)
 intCurrentSlide++;
	else
 intCurrentSlide = 0;

	if(currentContainer == sprContainer2)
 currentContainer = sprContainer1;
	else
 currentContainer = sprContainer2;

	currentContainer.alpha = 0;
	mcSlideHolder.swapChildren(sprContainer2, sprContainer1);

	slideLoader = new Loader();
	slideLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, fadeSlideIn);
	slideLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, showProgress);

//aqui é onde pega a imagem do xml

	slideLoader.load(new URLRequest(xmlSlideshow..image[intCurrentSlide].@src));

	mcInfo.lbl_description.text = xmlSlideshow..image[intCurrentSlide].@desc;
	mcInfo.lbl_description2.text = xmlSlideshow..image[intCurrentSlide].@desc2;

	if(xmlSlideshow..image[intCurrentSlide].@flag == "true"){
 mcInfo.tarja_mc.alpha = 100;
 mcInfo.tarja_desc.visible = true;
 mcInfo.tarja_desc.text = xmlSlideshow..image[intCurrentSlide].@desc3;
	}else{
 mcInfo.tarja_mc.alpha = 0;
 mcInfo.tarja_desc.visible = false;
	}
	mcInfo.lbl_count.text = (intCurrentSlide + 1) + " / " + intSlideCount + " Slides";
}

function showProgress(e:ProgressEvent):void {
	mcInfo.lbl_loading.text = "Carregando..." + Math.ceil(e.bytesLoaded * 100 / e.bytesTotal) + "%";
}

init();
