X3Photo Gallery Forums

Hi all,
This is my first time posting here and I'm not sure if it goes under this section.
I have a problem when I launch the V2 gallery, some pages in a particular shows 30 images per page while other shows like 100+ images per page. It so annoying to look at images that 100+ on a page, can someone show me how i can make every page display only around 20-30 thumbnails?

Thank you
