I've looked through this and re-looked through it many, many times. I can't find what's wrong with the code. In IE it works great, but in all NS versions (except 6) the table is about twice as wide as I specify. It appears to "push" further over further than I specify at the cells which house the "earthlightssmall3.jpg" and earthlightssmall4.jpg:"

<table width="450" cellpadding="0" cellspacing="0" border="0">
<tr>
<td colspan="3" width="450" height="75"><img src="../graphx/earthlightssmall1.jpg" width="450" height="75" border="0" alt="Earthlights"></td>
</tr>
<tr>
<td rowspan="2" width="100" height="150"><img src="../graphx/earthlightssmall2.jpg" width="100" height="150" border="0" alt="Earthlights"></td>
<td colspan="2" width="350" height="75"><img src="../graphx/earthlightssmall3.jpg" width="350" height="75" border="0" alt="Earthlights"></td>
</tr>
<tr>
<td colspan="2" width="350" height="75"><img src="../graphx/earthlightssmall4.jpg" width="350" height="75" border="0" alt="Earthlights"></td>
</tr>
<tr>
<td colspan="3" width="450" height="50" align="center" valign="middle"><p><font face="Courier New, Courier"><span style="Font-Size : 14px">Earthlights.jpg (courtesy of <a href="http://www.nasa.gov/">NASA</a>)</span></font></p></td>
</tr>
</table>

Thanks in advance for any code-solving!
