1 


request = new URLRequest(gameURL);
 loader = new Loader();
loader.load(request);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,imgLoaded);
            loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,imgProgress);

        
function imgLoaded(e:Event){

org_game_w = loader.contentLoaderInfo.width;
org_game_h = loader.contentLoaderInfo.height;
            
var loaderW:int = loader.width;
var loaderH:int = loader.height;
            
         trace(loaderW); // 271
         trace(org_game_w); // 780
           
        trace(loaderH); // 48
        trace(org_game_h); // 600
}

What there is so much difference?

Awaiting your response.

Thanks in advance
