Another Array question

I have this way of clicking through an array (called images) of jpg’s. How to make my rew button allowing me to go backwards? Or is there an easier way to do this?


var ffCount:Number = -1;
function ffLarge(event:Event):void {

	if (ffCount < images.length) {
		ffCount ++;
		var ffLarge:URLRequest = new URLRequest(images[ffCount]);
		imageContainer.load(ffLarge);
	}
}

ff_mc.addEventListener(MouseEvent.CLICK, ffLarge);
