Center my ads?

I managed to get the ads runninng on my forum at sandalspictures.com but if you scroll down you'll see they are shifted to the left. I do not really know PHP well. Could someone tell me how I might get the ads centered under my forum so it looks better?

 

<?php
ini_set ("include_path", ini_get ("include_path") . ':../:../../:../../../:../../../../');
include ('ad_network_xxx.php');
echo '<br><DIV align=center>';
echo $ad_network;
echo '</DIV>';
?>

 

Actually, the XHTML valid version would look like this:

<?php
ini_set ("include_path", ini_get ("include_path") . ':../:../../:../../../:../../../../');
include ('ad_network_xxx.php');
echo '<br /><div style="text-align:center; width:800px;">';
echo $ad_network;
echo '</div>';
?>

but instead of 800px, you set it to however wide your forum is. it will float the text in the center. using align="center" is not valid HTML and will not work in some browsers.

Just FYI

 

Two more noob questions.

Do I place this code in my templates where previous I just put $ad_network included in the install instructions. Does this code replace that or work with it?



Thanks again
John

 

the code replaces that.
