Gallery Unlocker (Simple) Should work on any update if not you can try and edit try .rpy file on your own
file location bizzareholyland/renpy/common and open the 00gallery.rpy file with notepad
then scroll down or use the find function of this string
-----
class __GalleryButton(object):
def __init__(self, gallery, index):
self.gallery = gallery
self.images = [ ]
self.conditions = [ ]
self.index = index
def check_unlock(self):
for i in self.conditions:
if not i.check(True):
return
True
for i in self.images:
if i.check_unlock(False):
return
True
return False
