title: Show an updating image in just one window
body: <p>I want to show a jpg in a window which updates multiple times per second.
  I have coded a very very compact program with just 100 lines of code (a neural network which creates the image) and don't want to put in another 100 lines of code to just show the image.
  Is there anything I can do to solve this problem?</p>
  
  <p>Many thx, jj</p>
