title: Split an image into parts
body: <p>I know that there are a lot of topics about this, but none really fits into my problem.
  I need the attached image (<a href="http://www.bilder-hochladen.net/files/big/1fby-6t-555d.png" rel="noreferrer">link</a>) divided into multiple sub-images and I search for the easiest way to do this.</p>
  
  <p>The image should be saveable. I tried BufferedImage, which lacks a useful constructor for this.</p>
  
  <p>It doesn't have to be java. A simple tool who can do this would also do the job. Note: I have to get ~567 images out of one. I found "online image-splitters", but none was able to split the image into more than 32 parts.</p>
