1) Script Title: Lightbox image viewer 2.03a

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...box2/index.htm

3) Describe problem:

I'd like to change the navigation from clicking on the image to two arrows left of the 'close' button. But while I'm not that familiar with javascript, I can't get it to work.
I've tried though, but the script never worked, it did without the changes to the javascript. But everything I tried (replacements of parts of the script) resulted in errors or malfunctioning.

Can anyone help?
