2 sites, 1 nextgen gallery

howdy all
i have 2 wordpress sites, on the same webhost.
on one of them i have nextgen gallery installed with some albums and pictures, and i want to have exactly the same albums and pictures on my second website (again, same host).
i have installed nextgen plugin on the second website as well but can’t seem to find a way to import the gallery from the first website.
just want to avoid having to upload all the pictures all over again.
thank you for your help
