    Need to click on the thumbnail and show the enlarged picture

      I am missing one last piece to my picture gallery that I need help on.

      From a datagrid, I am selecting a "city" that has a number of pictures associated with it. When the city is selected followed by pressing the "display pictures" button, a tile of pictures is presented.

      Each picture resides in a file on my website. They occur in order as "picture01", "picture02", etc depending on how may pictures have been taken for each city.

      What I would like to do is click on the thumbnail and show the enlarged picture in the container just below the tiles.

      That is where I am stuck.

      I want to be able to click on the thumbnail and fire off an event so I can set the source of my other container (with a larger height/width) to the thumbnail selected.

      The SWF can be found here:


      Here is the code.

      <?xml version="1.0" encoding="utf-8"?>
      <mx:Application xmlns:mx=" http://www.adobe.com/2006/mxml"

      // City Name Selected
      private var cityName:String = "";

      // Array for a single location pictures
      private var repeatArray:Array = new Array();

      // Function: Create City Pictures
      private function setRepeaterArray(pix:int):void {

      // Set Initialize Interim Array an Set the Number of Items in the Array

      var xArray:Array = new Array();
      var xMax:int = pix;

      // Populate the array
      var i:int;
      for (i = 1; i <= xMax; i++) {

      // Set the array used to repeat images to the interim array

      repeatArray = xArray;
      cityName = myGrid.selectedItem.city;

      <mx:VBox width="200" height="100%" verticalAlign="top" horizontalAlign="left">
