Depends how many knots you know, if you're allowed to put screws into the wall, etc- these are all valid ways of hanging pictures.

If you mean "in how many different orders" can you hang eight pictures, read on.

For the first spot, you can pick any of your eight pictures to hang, so there's eight ways to fill the first space. Now you have seven pictures left over, so you have seven ways to fill the second spot, etc. The final answer is 8*7*6*5*4*3*2*1, which we write as 8! and is equal to 40320.
