Is is possible to add "Load More Stories" button in advanced editor?

Hi,

I want to have a custom page that looks like this:

http://thepsychreport.com/psychlist-test-3/
password: enfoldhelp

But I only want 21 or so picture blocks to load at a time. Then it would be great to have “Load More Stories Button”

I know the masonry gallery has this option, but I can’t use masonry in this case because I will be describing and linking to other sites underneath the image and the masonry gallery is a bit too limited for the customization i will need there.

is there a way to add a “load more stories” at certain intervals on the page?

thanks

evan
