title: Reload php image (captcha)
body: <p>This is a captcha image with a link that will reload the picture if the user wants. This code works only in Google Chrome. How do I make it work in other browsers?</p>
  
  <pre><code>&lt;img id="captcha" src="captcha.php"&gt;
  
  &lt;a id='reload'&gt;Refresh now&lt;/a&gt;
  
  $('#reload').click(function(){
      $('#captcha').attr('src','captcha.php')
  })
  </code></pre>
