If you battle solving sliding-puzzles, then I suggest you first follow this link. It will explain how to solve, especially the last 2 rows. See the 1st comment.
If you know how to solve sliding puzzles, then look here for how the picture will look when completed:
Start at the top left with the painting, then the Mannequin's head, then the big clock.
For the last 2 rows, do the dog on the right and work your way to the left.
So, go ahead, slide & solve the picture!
