title: How does hiding files in jpeg file works
body: <p>I was reading an article explaining <a href="http://www.online-tech-tips.com/computer-tips/hide-file-in-picture/" rel="nofollow noreferrer">How to Hide Files in JPEG Pictures</a>.</p>
  
  <p>I am wondering how it's possible for a file to contain both jpeg data and a rar file without any visible distortion either to the image or to the compressed file.</p>
  
  <p>My guess is that it has something to do with how either the compressed file or the jpeg file is represented in binary form, but I have no idea how this works.</p>
  
  <p>Can someone elaborate on that?</p>
