Check this code:
private function fileReference_complete(evt:Event):void {
var loader:Loader = new Loader();
loader.loadBytes(fileReference.data);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,loaderCompleteHandler);
}
private function loaderCompleteHandler(evt:Event):void{
img.source = evt.target.content;
}
So you need to use a loader in order to create the bitmap object.
