         var div = document.getElementById("imageViewerContainer"); 
         // Create a new image viewer instance 
         var createOptions = new lt.Controls.ImageViewerCreateOptions(div); 
         var imageViewer = new lt.Controls.ImageViewer(createOptions); 
         // Load an image into it 
         imageViewer.imageUrl = "http://localhost/images/image1.png";
