I was unable to find information regarding pagination in the manage pictures mode. I set the &pics_per_page but it only reflects in the front end. To edit a large gallery it would be difficult to have them all on one long page.
No pagination for manage mode, and yes, I know it’s bad.

It’s not bad for smaller galleries (which I think is the original intention of MG), but for larger galleries it would would be a nice feature. I will look into this.
