Assuming the question is that you have 5 pictures and want to know how many different ways you could put 3 on a wall from left to right: There are 5 choices for the first picture; for each of these there are 4 choices for the second; and for each of these choices there are 3 choices for the third, meaning a total of: 5 x 4 x 3 = 60 ways that 3 pictures can be arranged from 5.
8! = 40320 ways.
There are 30 ways.
