Ajax - drag and drop gallery

I'm currently using this script ([login to view URL]) This script doesn't allow me to SHIFT and click multiple images to move. I need this script to allow me to move multiple images at a time. We use it to re-arrange pages and sometimes have 100s of pages so I need to be able to move multiples at a time. More info and to download this script is at: [login to view URL];whichScript=floating_gallery
