Linking rotator pictures to VM catagory

Hi,
I have the rotator working fine, expect now I want each image linked to a VM catagory.
The documention mention "Link for this image, starting with http://. You can use internal or external links (internal link example www.yoursite.com/index.php , or external link www.google.com "

The catagory I want to link to is "http://localhost/1stop/administrator/index3.php?option=com_virtuemart&page=&category_id=20&category_parent_id=0" but not sure which part of this link to include so when clicked it goes to catagory instead of the VM form.

I am currently building in Localhost ... once uploaded to sever this link becomes obsolete? do I then need to re-link??

Thanks

If you use absolute links you will need to re-link, or you can put relative , that is infact just query string with backslash in front:

/?option=com_....
