title: Basic image rotation with jQuery
body: <p>I'd like to test banner (two css background images) and rotate them randomly on each page reload. Is it possible to achieve something like that without using any plugins? </p>
  
  <p>I just need to rotate two images, which is basically just <strong>swapping css classes randomly</strong> on the banner element, on <strong>each reload</strong>.</p>
  
  <p>Many thanks.</p>
