Hi, I have the same problem. Found the aboe mentioned setting, changed it to per_page = 999 but it still doesn’t diaplay all photos from a photoset. It displays more than 100 yes, but still not all. For example photoset with ~670 pics, only 500 are displayed. Is there another limit somewhere? Thanks.
