in the first two pictures the girl is walking UP the stairs. in the second two pictures the people are walking DOWN the stairs. in the first two pictures there is only one person walking up or down the stairs but in the second two there are 2 or more people doing it. Also in the first two pictures the girl is walking on a stair that is in the house or is linked to it, as in the last two the people are somewhere outside the house
