By default, the click on an image calls a JavaScript function in the html page. In this page, this function is present:
function selected(param){ window.open(param); }
The param is the url of the webpage. You specify it in the coverFeed.xml:
<cover> <img><![CDATA[plane.jpg]]></img> <desc><![CDATA[Plane]]></desc> <param><![CDATA[http://www.google.com/images?q=plane]]></param> </cover>
Since the source codes are provided, a cleaner approach is to modify the .as classes to open the url directly:
In the fileItemMediator.as, modify the contentClickListener function to open an url:
navigateToURL( new URLRequest( _param ), "_blank");
Also don't forget to import (add on top of the class):
import flash.net.navigateToURL;
