To access what the loader loaded, use loader.content reference. If you are loading an image, you can retrieve its raw data via (loader.content as Bitmap).bitmapData , of course first check if it's so via if (loader.content is Bitmap) . Also, you need to do all of this after your loader will finish loading, it'll send an event indicating this.

...
loader.load(urlRequest);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderComplete);
...
private function loaderComplete(e:Event):void {
    // now your image is fully loaded
    trace(loader.content.width);
    // etc etc, whatever you need to do with your image prior to 
    // addressing it from elsewhere.
}
