Stopping NextGen from forward to other albums

There are two tweaks i would like to make to my nextgen galleries that I need help on.

I have galleries with 40 or so pictures that are divided into two pages. You have to click on “2” to view the next set. Is there a way to have them all on one page or have it so that if you are on set one and click next during the slideshow it continues automatically.

The second problem is that I have multiple galleries on one page. When you get to photo 20/21 on the first album and hit next it opens the first photo of the next album isntead of keeping them separately. I would love some guidance.
