Do you have this pagination problem when using another template ?
Do you have "Pic Approval" turned on ?
Do each of your 25 personal galleries have at least 1 photo in them ? If a user has created their personal gallery, but has not yet uploaded any pics, then they will not appear in the list.
everywhere there is a more than 1 picture, where for 19 photos the maximally set number is represented only by me in adminke ( amount of pictures on a 1 page). And a "1 page is always written from 1", even if them it must be already 2. Also same on a subSilver template
