Several pages for a gallery?

First of all, thanks to the developer for this fantastic pluguin and sorry about my english

I wonder if it is possible to have a gallery with some pictures (for example 50) and don't see all of them in the same page. It is possible to have first a few of them (for example 10) and the click on a next button and other ten pictures appear and so on??

And another question... I have seen in other posts some people asking for a solution of center align for vertical pictures where they are mixed with landscape ones. Because in my gallery the vertical pictures are too close to the left.



Thank you very much for your help and regards from Spain!
