Code:
<table border="0" width="960" cellpadding="0" cellspacing="0" align="center">
<tr>
<td><div style="margin: 0 auto;" align="center"><a href="index.php"><img src="/ukmmabanner.jpg" border="0" alt="UK-MMA" /></a></div></td>
</tr>
</table>
assume you mean you want the image slap bang in the centre? you can do it using a table as above or you could completely do away with the table and use a div
Code:
<div style="margin: 0 auto;background-color: #ffffff;width:960px;" align="center"><a href="index.php"><img src="/ukmmabanner.jpg" border="0" alt="UK-MMA" /></a></div>
