Table background image problem

I'm trying to put a background in my table data section but i#m having no luck. It's been a while since i've made any websites but the last time i did i used this same method and now it's not working. Can anyone help ?

The page i'm working on is and i'm trying to get the coding marked in bold to work:

<TABLE WIDTH=1000 BORDER=0 CELLPADDING=0 CELLSPACING=0>
<TR>
<TD COLSPAN=5>
<IMG SRC="/lay_01.jpg" WIDTH=1000 HEIGHT=363 ALT=""></TD>
</TR>
<TR>
<TD ROWSPAN=4>
<IMG SRC="/lay_02.jpg" WIDTH=42 HEIGHT=537 ALT=""></TD>
