title: master page images not showing on child pages
body: <p>This is probably something really simple but I cant see what!
  Any images I have in a masterpage aren't showing up in child pages,
  all I get is the box with the red cross in it.</p>
  
  <p>I don't think Ive done anything different from usual and it's not something that's
  happened in other sites so im kinda scratchin my head with it.
  Any ideas are appreciated!</p>
