Everybody has notepad, Dux. Open up the folder where your game is, go to renpy, go to common, go to 00gallery.rpy
Search, 'if not renpy.seen_image(i):' and change the false value under it to true.
Next time, just look amongst the comments. You might be a lurker, like me, but that's no excuse to be ignorant.
Crank safely.
