title: Cannot show image from STATIC_FOLDER in Flask template
body: <p>I set folder for static files like this</p>
  
  <pre><code>app.config['STATIC_FOLDER'] = 'tmp'
  </code></pre>
  
  <p>In template i use img tag to show an image stored in /tmp:</p>
  
  <pre><code>&lt;img src='IKE2low.jpg' width="200" height="85"&gt;
  </code></pre>
  
  <p>In firebug i see 404 error instead of image. Please tell me what did i do wrong?</p>
  
  <p>Thanks in advance.</p>
