as3 moving image from one mc to another - actionscript-3

Question

With the code below I created some imgMcA and some imgMcB then I loaded images into imgMcA ones. ImgMcBs have no image at that moment. So if one of imgMcA is clicked the image should be transferred to one of the empty imgMcBs (may be randomly) and if imgmcB is clicked later the image should move back to its imgMcA back. I could not find out how I can accomplish this.
Thanks in advance
function imageList(mcname, img, index){
var imgMcA:MovieClip=new MovieClip();
imgMcA.graphics.beginFill(0x000000);
imgMcA.graphics.drawRect(0,0,imgWidth,imgHeight);
imgMcA.graphics.endFill();
imgMcA.name=lemma;
imgMcA.addEventListener(MouseEvent.CLICK, moveImage);
var imgMcB:MovieClip=new MovieClip();
imgMcB.graphics.beginFill(0x000000);
imgMcB.graphics.drawRect(0,0,imgWidth,imgHeight);
imgMcB.graphics.endFill();
imgMcB.name=index;
addChild(imgMcB);
var imgLoader:Loader = new Loader();
imgLoader.load(new URLRequest(img));
imgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, changeProperties);
imgLoader.mouseEnabled=false;
imgMcA.addChild(imgLoader);
}
function moveImage(evnt:MouseEvent){
}

You could linked mcA & mcB by adding them to the same parent.
function createBlock():void
{
var imgLoader:Loader = new Loader();
//add the loading code here...
var mcA:Sprite = new Sprite();
var mcB:Sprite = new Sprite();
// add Click event listeners for both Mcs here...
var parent:Sprite = new Sprite();
//add Children
parent.addChild(mcA);
parent.addChild(mcB);
addChild(parent);
}
function mouseClickHandler(event:MouseEvent)
{
var dispatcher:Sprite = event.currentTarget as Sprite;
//if you added a Loader to it
if( dispatcher.numChildren > 0)
{
//retrieve the image
var img:Loader = dispatcher.getChildAt(0);
//identify the parent
var parent:Sprite = dispatcher.parent;
var index:int = parent.getChildIndex(dispatcher);
//identify the receiving MC
//of course this only works with two children!!!
if(index > 0)
var receiver:Sprite = parent.getChildAt(0) as Sprite;
else
receiver = parent.getChildAt(1) as Sprite;
//add the image to the other MC
receiver.addChild(img);
}
}
The rest is not too complicated to achieve. You will need to use a Boolean and add a TextField. If the TextField contains text, set the Boolean to true.
It may be worth looking at Classes or you could use an Object as a container for the MovieClips, the TextField and the Boolean, although a Class will give you more flexibility...
With a Class, you wouldn't have to iterate in order to find what does what. Your Click listener would look something like this:
private function mouseClickHandler(event:MouseEvent)
{
receiver.addChild( image );
if( hasText)
imageReturn();
}
