Neither. im.thumbnail() modifies the existing image object by
converting it to a thumbnail. In Python such methods by convention
return None.
The documentation explicitly mentions that:
Also note that this function modifies the Image object in
place. If you need to use the full resolution image as well, apply
this method to a copy of the original image. This method returns
None.
Indeed, the purpose of returning None is to remind that the method does
mutation in place.
In [4]: thm = im.thumbnail((200,200))
In [5]: type(thm)
Out[5]: <type 'NoneType'>
Instead of thm, simply keep using ihm.
