Nextgen gallery

Hello,

just stumbled upon wordpress last week and trying to set up a blog for my friends. 🙂

what i’m trying to do is, when users upload pics, that they will show if you click on the gallery tab on my blog.

Do i have to do this manually everytime someone post a pic in a comment?

My gallery tab will be a collection of all pics being upped on the blog.

Or do users have to click on the gallery tab and start an album there selfs?

A bit confused here. 🙂

Thx.
