Well, just at a glance I can see you're missing a couple table cells. Note the tested table below has 3 table rows. The top and bottom table row contain 3 table cells. The middle table row only contains 1 table cell. Adding the colspan="3" where indicated may help. I didn't scour the code for any other problems so more may exist.
HTML Code:
<table border="0" width="100%" cellpadding="0" cellspacing="0" align="center">
<tr>
<td width="853" align="right">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="26%" height="147" rowspan="2" valign="top"><img src="images/HR/hdr_01.gif" width="250" height="93"></td>
<td width="1%" rowspan="2"><img src="images/HR/hdr_02.gif" width="58" height="147"></td>
<td width="73%" height="84" valign="top" bgcolor="415B8F"><img src="images/HR/hdr_03.gif" width="100%" height="15"><br>
<br> </td>
</tr>
<tr>
<td height="62" valign="bottom"><img src="images/HR/hdr_06.gif" width="92" height="62"><img src="images/HR/hdr_07.gif" width="191" height="62"><img src="images/HR/hdr_08.gif"><img src="images/HR/hdr_09.gif" width="254" height="62"></td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table></td>
</tr>
</table>
change the middle tr to:
HTML Code:
<tr>
<td height="62" colspan="3" valign="bottom"><img src="images/HR/hdr_06.gif" width="92" height="62"><img src="images/HR/hdr_07.gif" width="191" height="62"><img src="images/HR/hdr_08.gif"><img src="images/HR/hdr_09.gif" width="254" height="62"></td>
</tr>
I also wouldn't code a table cell with an 853pixel width. You're pretty much ensuring than 50% of your users will need to scroll horizontally tosee the entire page. Not good.
