title: Thin line between horizontal <img> and <div>
body: <p>I have a thin white line between a black image and a div with a black background on a page with the body background set to white.  I have tried setting <code>border: 0 !important</code>amongst other things but I just can't get rid of it.</p>

  <p>Is there anyway of removing this?</p>
