Question about a DHTML and JS menu

[lvt]

This is the menu I want to modify

http://207.45.188.250/~lvt/test/test.html

The problem is I cannot remove the black vertical line at the left side of each image , can someone please help me !!!

The main JS script is here :

http://207.45.188.250/~lvt/test/js_menu.js

other parameters can be seen by viewing the source of the above page.

Thank you.

That is one maintenance nightmare of a script. I think you need to ask whoever wrote it about this.
