var request:URLRequest;

var startPageHeight:Number = stage.stageHeight;


picURL=new URLRequest(nameImages);
picLoader= new Loader();
picLoader.contentLoaderInfo.addEventListener(Progr essEvent.PROGRESS,onLoadProgress);
picLoader.contentLoaderInfo.addEventListener(Event .COMPLETE,onLoadComplete);

picLoader.load(picURL);
function onLoadProgress(evt:ProgressEvent):void {
var titileLoaderLoad:Number = Math.round(100 * (evt.bytesLoaded / evt.bytesTotal));
MovieClip(parent).loadingImages.progress.text = titileLoaderLoad + "%";
MovieClip(parent).loadingImages.gotoAndStop(titile LoaderLoad);
}
function ResizeHandler(event:Event):void {
var startPageWidth:Number = stage.stageWidth;
var startPageHeight:Number = stage.stageHeight;

Tweener.addTween(MovieClip(root).mcMainGallery, {x:startPageWidth/2 - MovieClip(parent.parent).width/2,
y:startPageHeight/2- MovieClip(parent.parent).height/2,

}

addChild(picLoader.content);
stage.addEventListener(Event.RESIZE, ResizeHandler);
MovieClip(parent).play();
MovieClip(parent.parent).picW=MovieClip(parent.par ent).width/2;
