fade external image

[pcmac]

Hi

Can anyone help me with fading in external images into the movie clip please?

Here is my code:

 function loadImage(url:String):void {
                    imageLoader = new Loader();
                    imageLoader.load(new URLRequest(url));
                    imageLoader.contentLoaderInfo.addEventListener(ProgressEven t.PROGRESS, imageLoading);
                    imageLoader.contentLoaderInfo.addEventListener(Event.COMPLE TE, imageLoaded);
          }
          loadImage("imgs/" + pic + ".jpg");
 
 
         function imageLoaded(e:Event):void {
                    if (pic_mc.loadedImage) {
                    pic_mc.removeChild( pic_mc.loadedImage );
                    }
                    pic_mc.loadedImage=imageLoader;
                    pic_mc.addChild(imageLoader);
          }

Many thanks
