title: Relative links with subdomains
body: <p>I've just added a subdomain to my website, but can I point it to files in the main website with relative links? Like in the way that ../ goes back a folder, can you tell it to remove the first part of the url?</p>
  
  <p>Also, I've just seen perhaps it's better putting the image folder as a subdomain too, is it worth doing this?</p>
