Thumbnail image Link

I have bought the Plug-IN and made all the changes in the thumbnail view I wanted to make. I also added a URL to images in the Huge IT image gallery. When I am publishing my page and clicking on the image, it is first zooming out, if I cancel that, a slier comes up. I simply want that when someone clicks on the image it should take the viewer to the URL I have set in the image gallery. Find link for clarity: http://sonalsrivastava.com/2146-2/.

Click on amt image and see the issue.
