In Episode 1 you will be using the computer game to make progress. It's a text based game. You will need to take the note and key from glove compartment, go around to turn on generator (access to door using key) and flipping on light. The most confusing part to me was the "landing" area which is basically the stairs. This is a location you go to from the rooms and bathroom.
Anyways, the pictures are in the wardrobe in the sister's room. Open it and look around, then look ay pictures.
