Javascript Cart Button

[Luno1599]

Hey,

I am a photographer, I have a website with a gallery. The gallery is ran by Javascript, when you click the thumb nail the script will take the t off the same so say it was 001t.jpg it will make it 001.jpg and put that file in the div tag called image

However I want to be able to sell them using paypal's shopping cart...
however I need to put the gallery name and image name in the name on the button but I cant code javascript so can someone code me one that will update this for me and then put the code it makes into a div tag called cart?

PLEASE HELP!!!

Here is the paypal code
