You've included the image twice in the body.
Replace the entire body (from, and including, <body> to, and including, </body>) with
Code:
<body class="full-page-image">
<div class="full-page-image">
<img alt="Map" src="../images/00004.jpg" class="full-page-tall"/>
</div>
</body>
and
add the following the CSS file:
Code:
body.full-page-image { margin:0; padding:0; }
div.full-page-image { margin:0; padding:0; text-align:center; }
img.full-page-tall { margin:0; padding:0; height:100%; width:auto; max-width:100%; }
