Nextgen Gallery – Permalink Problem

Hi, I create a father page, and it works like a portfolio, inside it, there are several projects, and I want to list all of them in the portfolio.php page(wich has the portfolio template)

I managed to list the album beautifully, but when I click on the galery, it stays in .com/portfolio/, not in .com/portfolio/sun/ for ex.

I can`t have one template for every gallery, because I put them as default (page.php).

anyone know how to do that?

Sorry if things got a little confuse!

tkz!
