I am stuck on the doll room puzzle "Flipping out" where you have to flip the picture its original form.

I tried this puzzle about 20 times, because it's impossible to get it into its right shape.
Appearantly this is a bug from the ScummVM emulator:

Any idea what to do?! Restarting it over and over is just stupid.

The book of riddles honestly is pretty much useless unless you want to teleport fast to your current room.

As for the other suggestion, sure, I can try all day just resetting the puzzle.

EDIT: Thanks, the book helped out. Sorry, forgot it can solve the riddles automatically 8(

It's a bug that was already in the original game. The game randomly deals unsolvable positions. Just reset the puzzle if you see that the position is unsolvable (move the mouse cursor to the bottom until the brain appears and click to reset the puzzle) chances are that it is solvable now.

The "puzzle" itself is very very trivial if it actually is in a solvable state.
