How do I combine two plugins?

Hi people,
 
I was wondering if you can help me with a small challange. I have a website, where I have added two jqyery plugins:
 
1) Jquery Lightbox2
This excellent plugin enlarge pictures on mouseclick.
2) Jquery Loupe
Also an excellent plugin, which works as a image magnifier on mouseover.
 
now, what I want to do is to combine these two plugins in order to get the following feature:
when i want to study an image/picture, I click on it to enlarge it (Lightbox2) and on the enlarged picture I can mouseover to get the "magnifying glass"(Loupe) in order to study it in more detail.
 
I have tried to implement the Script from "Loupe" into the Lightbox2.js plugin, with no success.
I am not very experienced  in javascript, so I hope there are som experts out there who knows the drill.
 
looking forward hearing from you.
 
Br,
Jakob
