title: If any content is loading show a loading gif
body: <p>My site is pretty slow. Yep, moving will solve the problem. But in the meanwhile I want to display a loading gif in the top right corner if any content is loading. My site is running Magento. So I was thinking to get it global, I have to customize the prototype.js for Ajax calls. Further I have to put a small JavaScript on every page (for the normal page load).
  Any ideas how I can get this working? I already looked into the prototype, but I couldn't find the specific function.</p>
  
  <p>Every help is much appreciated.</p>
  
  <p>Thank you!</p>
