the gallery was the first thing i programmed for playak from groud up, and that was 6 years ago. the software needs a general overhaul, i know. sounds like a winter project. until then, just use another sorting method to see more. e.g. click on the rating header above the list to sort by rating, and then if you click on it again, you'll get the list by reverse rating, so you can see them all.
in the beginning we just never had galleries with more than 10 photos or so
