Right above the logo picture, we can see there is a table row with the following HTML:

          <tr>
            <td height="19" background="templates/skyline/images/topmenubg.jpg">
              <?php mosLoadModules ( 'top' ); ?>
            </td>
          </tr>

What this means is that this row holds a background image, plus the "top" position. Let's try hiding this row with a style="display:none" attribute.
