Discovering this in a template for one of work's webapps:

  <table>
   <tr>
     <td width="99%"><div class="header1">Page Heading</div></td>
     <td width="1%"><img src="static/images/1x1_transparent.gif"/></td>
     <td width="150"> </td>
   </tr>
 </table>

Yes. That is the markup they have given a PAGE HEADING. It serves no other purpose. JUST A PAGE HEADING.

ETA: for those playing at home, here's what a standards-compliant, semantically marked-up, beautiful page heading looks like under its skirts:

<h1>Page Heading</h1>
