As usual, Wige is correct. Here's what he's trying to say:
You can apply a CSS style specifically to the image table by assigning it an id. There's no need to specify the cellpadding in the table tag and the CSS style will work the same in any browser.
For example:
Code:
<style>
table#imagetable td{ padding: 10px; }
</style>
<table id="imagetable" border="1">
<tr>
<td>put an image in here</td>
</tr>
</table>
