Image Load Failure

Question

I have a program that dynamically loads images from a
database, loads them mirrors them, then adds them to the
rawChildren of the Canvas, however, if an image does not exist is
there a way to test the image existence and if that fails load a
'dummy' image? I have the following code:
public function imgLoader():void
var context:LoaderContext = new LoaderContext();
context.checkPolicyFile = true;
this.img = new Image();
this.img.source = this.img_path;
this.img.maintainAspectRatio = true;
this.img.scaleContent = false;
this.img.autoLoad = false;
this.img.loaderContext = context;
this.img.addEventListener(Event.COMPLETE, handleImageLoad);
try {
this.img.load();
} catch(err:*) {
Alert.show("Cannot load Image: " + this.img_path);
then of course i have a event listener function that does all
the fun img stuff once the image loads.
However, if the image does not exist, then the Event.COMPLETE
is never called, the try is "successful" as far as Flex is
concerned, is there an event listener that I'm missing that fires
if the load fails?

As it turns out this was easier than expected....
I added the following listener:
this.img.addEventListener(IOErrorEvent.IO_ERROR,
handleImageError);
function handleImageError(e:IOErrorEvent):void {
Alert.show("cannot load image: " + img_path);
and there it was the Alert that i was expecting when my image
path fails!
