Try this alteration (in bold) to the first table in your code:
-------------
<TABLE BORDER="0" CELLPADDING=0 CELLSPACING=0 width="100%">
<TR>
<TD ROWSPAN=2><IMG NAME="DRAFT90" SRC="images/accreditations.gif" width="198" height="109"></TD>
<TD WIDTH=523 bgcolor="#EAE6E0"><IMG NAME="DRAFT91" SRC="images/logo_t2.gif"
BORDER=0 width="523" height="102" ></TD>
<TD bgcolor="#EAE6E0" width="100%"><img src="images/spacer.gif" width="5" height="5"></TD>
</TR>
....
---------------
It has the effect of adding all "extra" space in the table width to that particular column. Necessary since you do not have widths specifically set for all of your columns, and you are making the width of your table relative. Hope this helps.
