I couldn't understand perfectly what you told... but in guess,
Are you using images in <TABLE><TR><TD>?
if you are using like this,
<table>
<tr>
<td background=1.gif></td>
<td background=2.gif></td>
<td background=3.gif></td>
</tr>
</table>
this code may help you.
<table>
<tr>
<td background=1.gif width=20></td>
<td background=2.gif width=20></td>
<td background=3.gif width=20></td>
</tr>
</table>
(1.gif, 2.gif, 3.gif are 20x20 gif images)
Sometimes, the browser can't make a table which contains some images, rightly.
