Flex中如何利用PopUpManager类创建一个弹出Image控件的例子

<?xml version="1.0" encoding="utf-8"?>

            modalTransparencyColor: black; 
            modalTransparencyDuration: 500; 
        } 
    </mx:Style> 
  
    <mx:Script> 
        <![CDATA[ 
            import mx.controls.Image;

            private const IMG_PREFIX:String = "http://www.helpexamples.com/flash/images/"; 
  
            private function popIt(src:String):void { 
                var img:Image = new Image(); 
                img.addEventListener(MouseEvent.CLICK, img_click); 
                img.addEventListener(Event.COMPLETE, img_complete); 
                img.load(IMG_PREFIX + src);

            private function img_complete(evt:Event):void { 
                var img:Image = evt.currentTarget as Image; 
                img.width = img.contentWidth; 
                img.height = img.contentHeight;

            } 
        ]]>

    <mx:ApplicationControlBar dock="true">

弹出自己定义的图片又该怎么做呢
