I was just examing the photo that is suppose to be the book cover for 
OoP US version. (I say suppose, because, I'm still not convinced) I 
noticed something strange. (or maybe it's just me)  All the flames 
from the candles, seem to all go in the same direction, normal enough 
right?  But if you look closer, the flames on the candles in the 
back, by the walls, on both sides (these are smaller ones) go in the 
opposite direction of the rest.  I don't know if it means anything, 
but from what I've read, the cover is a very important part of the 
book, they spend alot of time coming up with what will be on it. I've 
also read that the cover usually holds clues to what's inside. (This 
would be why I was examining it.)  

Well, I just wanted to see what every body thought.
