title: Missing ImageTk module with pillow and python 2.7
body: <p>I've installed pillow on Ubuntu 14.04.  I'm using python 2.7 for this project. There is no ImageTk module, although the <a href="http://pillow.readthedocs.org/en/latest/reference/ImageTk.html" rel="nofollow">pillow web site</a> says there is.  python finds PIL all right, but when I try to import ImageTk, the PIL compatibility layer (or whatever I should call it) tries to import the ImageTk module from the PIL module, and it's not there.  Other modules like Image, ImageChops and so on, are there.</p>
  
  <p>I need the ImageTk module so that I can use JPEGs with tkinter.  What do I need to do?  Alternatively, using pillow can I create PhotoImages from JPEGs in tkinter without the ImageTk module?  How?</p>
  
  <p>I've copied a terminal session below in case I haven't explained myself well.  Thanks for any assistance.</p>
