title: PIL.Image vs skimage.io: When to use each, and which (if one) is prefered over the other in general?
body: <p>I have been using Image for opening and getting pixel info, and have read things like "PIL is the future and blabla..", but I have seen that skimage is extensively used. </p>
  
  <p>Which one should I use for general image processing? I would feel more comfortable with this question answered..</p>
