Должно быть где-то так:

 
private function loadChild() {
    var _loader:Loader = new Loader();
    _loader.contentLoaderInfo.addEventListener(Event.COMPLETE, this.onLoadCompleteObj);
    _loader.contentLoaderInfo.addEventListener(SecurityErrorEvent.SECURITY_ERROR, this.onLoadErrorHandler);
    _loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, this.onLoadErrorHandler);
    _loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, this.onLoadProgressHandler);
 
    var req:URLRequest = new URLRequest('http://pic.************/uploads/091006/iPLkdgTS7u.jpg');
 
    addChild(_loader);
    try {
        _loader.load(req);
    } catch (error:Error) {
        onLoadErrorHandler(null);
    }
}
 
private function onLoadCompleteObj(event:Event) {
    trace('load complete');
}
 
private function onLoadErrorHandler(event:Event):void {
    trace("error: " + event);
}
 
private function onLoadProgressHandler(event:ProgressEvent) {
    trace(event.bytesLoaded,event.bytesTotal);
}
