title: Auto updating a php image every x seconds
body: <p>So I have div which contains a php as body background.
  Let's say it's image.php</p>
  
  <p>image.php display's a different image depending on the hour/day/month</p>
  
  <p>Now if my website remains open for more than an hour the same image is still displayed which is.. well not how it should be.</p>
  
  <p>However displaying the image works, It doesn't update and frankly, I don't quite know how to approach this.</p>
  
  <p>So here I'm not asking for someone to make this script for me, but rather point me in the correct direction to have a script that reloads the php file completely.</p>
  
  <p>Thank you in advance!</p>
  
  <p>EDIT: Sorry for making it unclear, I really need only the specified div bg to completely reload, not the entire webpage. That's where I get stuck on creating this.</p>
  
  <p>I know how to update an image but as far as I know, that image is already loaded on entering the website so it won't update furtheron, Reloading the entire page is also no-go since the image is placed in the header, and the header is not updating on page navigation since it contains an audio player</p>
