Masonary Gallerie preload / image navigation

Hi,

I’m using the Enfold theme for a private travel website.
I use the “Masonry Galerie” element to showcase a huge number of pictures on the website (link in private content).

I’m afraid there is a usability issue and I wonder if this can be fixed:
I display 15 pictures per page out of 100+ pictures in a galerie, as in the example URL. To load more pictures, I’ve included the “Load more” button as my Pagination option. This all works perfectly fine.

My issue is that most people click on an image and then start browsing images by clicking to the left and right with the arrows or using the keyboard. By doing so, the images will just loop after 15 images instead of continuing to load the next 15 images (and so on). Is there a way to change this?
