title: Encoding binary data in a PNG?
body: <p>I'm looking for information on how to encode a small amount of binary data (say, around 200 bytes) into a PNG through colors; essentially what <a href="http://torrentfreak.com/hidim-converts-torrents-into-png-images-090714/" rel="nofollow">Hid.im</a> does for <code>.torrent</code> files. Any information or springboard for a best practice would be stellar.</p>
  
  <p>Thanks!</p>
