Each of the pictures, which are interactive, comes with a brief description of the scene and includes new pictures of Harry at the Ministry of Magic and Harry sitting in Snape's potions room.
The last picture of Harry at the MoM has a description of the scene as follows:
In this shot, taken from near the end of the film, Harry is deep inside the ministry and sees, for the first time, the long corridor of the Department of Mysteries, gleaming in black ceramic tile, which has been haunting his dreams all year. This dream will guide him and his loyal friends down this corridor, toward a room filled with glass orbs--a set which will be completely digital in the film. One of those glass orbs holds the prophecy that binds Harry to Lord Voldemort and that seals Harry's fate. This corridor will also ultimately lead Harry toward his greatest battle, and the death of someone very close to him.
