assuming you're using 0.4.60...
Animation Gallery: 3rd page, 2 column last row -- Level 4, interact with the head of the decapitated girl (left side of room with green electricity)
CGI Gallery: 2nd page, 4th column 2nd row -- Level 4, get impaled THROUGH CHEST by spike and then decapitated by sawblade. Only available in the first sawblade room.
You can also attach pics of your galleries, that makes it easier to answer.
What did you think of the game? If you can rate/review I'd really appreciate it.
