title: How to specify mimetype of files with no extension in NGINX config?
body: <p>I have a server with nginx. And I have a lot of images - pngs and jpgs saved as files with no extension (like "123123123_321312").</p>
  
  <p>When I use tag "img" in html page, I get theese messages in console:</p>
  
  <pre>
  Resource interpreted as Image but transferred with MIME type application/octet-stream: "http://xxxx/images/1350808948_997628". jquery.js:2
  Resource interpreted as Image but transferred with MIME type application/octet-stream: "http://xxxx/images/1343808569_937350". 
  </pre>
  
  <p>Is there a way to make nginx add header with correct mimetype of the requested file?</p>
