Comparison: Importing an image using ActionScript 2 and 3

If you are going to develop flash based content using AS3, you should know it takes a bit more work to do simple things.  For example, say for inistance you want to load an image into a movie clip called “imgHold_mc” using ActionScript 2,  you could use the following code:

function loadImage() {
imgHold_mc.loadMovie(imgUrl);
}
loadImage();

-or-

var url:String = "imgUrl";
function loadImage(link:String){
imgHold.loadMovie(link);
}
loadImage(url);

If you wanted to do the same thing but using ActionScript 3, you would need to use the code bellow:

var imageLoader:Loader;
function loadImage(url:String):void {
imageLoader = new Loader();
imageLoader.load(new URLRequest(url));
imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded);
}
loadImage(imgUrl);
function imageLoaded(e:Event):void {
imgHold_mc.addChild(imageLoader);
}

-or-

var imageLoader:Loader = new Loader();
imageLoader.load(new URLRequest(url));
imgHold_mc.addChild(imageLoader);
