[Plugin: NextGEN Gallery] get nextgen gallery page url by ID

I have this website fotograf nunti iasi. I have a post. I put in custom fields ngg_gallery_id = 88 where 88 is the Id of a gallery. What I want is to be able to put link on the post page to the corresponding gallery with ID 88. How can I do that? In the previous versions of nextgen gallery I used <?php the_permalink() ?>?vezi=galerie but now it does not work anymore.

so how can I get the url of a certain gallery knowing it’s Id and using custom fields?
