title: Preloader - But only on homepage / first time
body: <p>I am workin on a photography website which should display a preloader with my logo. I've implemented this already.</p>
  
  <p>But now it shows up on every page.</p>
  
  <p>I would like to have it only the first time someone access the website, so when he switches through subpages, no preloader shows up. Also when he switches to the home = no preloader. But when he closes the site and access it again - the preloader should be visible.</p>
  
  <p>Is there a good solution for realising that?</p>
  
  <p>Thanks in advance for the help</p>
