I have no idea if this will help or not, but putting the background in the <TR> or <TD> tag may help. I find that Front Page sticks it way up in the commands, and that may cause a problem. I'd try doing it here, but I could really mess up the thread when it loaded an image. What I've got is:

  <div align="center"><center>    

<table border="3" width="300"    

bordercolor="#008080">    

    <tr>    

       <td width="40%"   background="your/graphic/goes/here"><p align="center"><
          font color="#FF0000"          size="7">Experiment</font></p>    

        </td>    

    </tr<>    

</table>    

</center></div>
