   var iv = $find("WebImageViewer1");
   var items = iv.get_items();
   var item = items.createItem();
   item.set_imageUrl("~/images/TestImage.jpg");
   items.add(item);

//The client side event ImageItemAdded takes two parameters, sender and e.
//Sender is the object which is raising the event

function WebImageViewer_ImageItemAdded(sender, e) {
   var imageviewer = $find("WebImageViewer1");

   var imageItem = e.getImageItem();

   // Set the added image to be visible in the image viewer
   imageItem.set_visible(true);

   // Get the index of the new image
   var imageIndex = imageItem.get_index();
