Image loading problem

[bluemagica]

private function getImage():void
            {
                fr.addEventListener(Event.SELECT,imgLoad);
                fr.addEventListener(Event.COMPLETE,imgExtract);
                fr.browse([new FileFilter("Images(*.png,*.jpg,*.bmp)","*.png;*.jpg;*.jpeg;*.bmp")]);
            }           
            private function imgLoad(e:Event):void
            {
                fr.load();
            }
            private function imgExtract(e:Event):void
            {
                var img_br:ByteArray = new ByteArray();
                img_br = fr.data as ByteArray;
               
                var loader:Loader = new Loader();
                loader.addEventListener(Event.COMPLETE,imgDisplay);
                loader.addEventListener(IOErrorEvent.IO_ERROR,imgLoading);
                loader.loadBytes(img_br);
                pathtxt.text = "Loading "+img_br.length+" : "+loader;
            }
            private function imgLoading(e:IOErrorEvent):void
            {
                pathtxt.text = "here";
                //imgProgress.setProgress(e.bytesLoaded,e.bytesTotal);
            }
            private function imgDisplay(e:Event):void
            {
                image = e.currentTarget.loader.content as Bitmap;
                imgPreview.addChild(image);
                pathtxt.text = fr.name;               
            }

When I run the above, it doesn't seem to trigger the imgDisplay or imgLoading functions(imgLoading was supposed to be progress event, but I changed it for testing).....it seems, the eventListeners are not working, any idea?
