Clone query

1) Script Title: Dragable elements Script

2) Script URL (on DD): http://dynamicdrive.com/dynamicindex4/image3.htm

3) Describe problem: Hi I love this script and am using it fine - however, my problem is that I can't work out how to clone the images.

I want to be able to drag copies of the images and leave the originals where they are.

Thanks so much if you could help.
