any idea how to unlock photo number 26 and last 3 photos on page 4? I tried everything and i just dont have a clue
26 is kind of tricky to get at the moment, you have to play against Jason after you've got pictures from the Secretary. If you did, you can tell him you're not happy with his reward and he'll give you another pic.
There will be other ways to get this pic later if you didn't get it so don't feel the need to replay everything just for it.
Last 3 pictures are of the secretary. Go to the reception and ask her for Ember many times until she leaves.
Then, the following days, come back (if she's there just leave and come back until she isn't). You'll eventually get to the last three pictures.
This is kind of a stupid way to get pictures, but more content will come to that part of the game... I'm actually working on it right now.
