I already have a lightbox script running a product gallery and do not wish to recopy a new set the images again for the popcard script which i want to use.

I was wondering how i can use the ecard system feture of remote cards with the following snipit and integrate into my existing lightbox gallery with a button that appends image url with the script location url?

http://site1.com/popcard.php?pu=http....com/image.jpg

SCRIPT LOCATION URL ?pu= IMAGE LOCATION FROM LIGHTBOX

Could anyone help by pointing me where to go?

I never written a custom javascript I've only done basic pop up boxes; I know i need to write a function to handle this and use the geturl thing but haven't got a clue where to look on the internet for particular advise

i really tried myself but cannot get anywhere.
