title: How do I create a set of image files from a PowerPoint file file?
body: <p>I'm creating a "slideshow room" web page. The user will upload a PowerPoint file that my server will use to generate a set of .jpg image files representing the slides to present in a custom "gallery viewer".</p>
  
  <p>I'm an experienced Python developer but I cannot find anything useful.</p>
  
  <p>How can I do that?</p>
