How to use lightbox.js in my page

Hello

I have a web page ( its in germany, but no problem as all code in english ).

http://www.schlenther-edelstahl.com/...toGallery.html

Now, i am using a gallery to display images, but i would like to use Lightbox2 plug in but only when i click on an "Enlarge Image" button.

The question i have is, when i click an image on the left hand side, is there anyway i can use the image name and pass it into the "Enlarge Image" button so it will show the image enlarged. So i basically need to Var = "Image Name" and make a call to that Var in the image button, but how can i do it ?

Thanks
