title: Python: default/common way to read png images
body: <p>I haven't found a standard way in Python to read images. Is there really none (because there are so many functions for so many custom stuff that I really wonder that there are no functions to read images)? Or what is it? (It should be available in the MacOSX standard installation and in most recent versions on Linux distributions.)</p>
  
  <p>If there is none, what is the most common lib?</p>
  
  <p>Many search results hint me to Python Imaging Library. If this is some well known Python-lib for reading images, why isn't it included in Python?</p>
