All images on one page

Hi Alexander, me again.
Thank you so much for your help the last time. It worked like a charm. I still use the theme and love it :).
What I would like though, is for all the images to fit on one page, so you don’t have to move to the next page(s) to view the rest of the images. Or perhaps a setting to specify how many images you want to show per page. Is something like that possible?
Thanks again.
