If you delete the banner in your cart admin are it deletes the entire thing including the footer links for your site. I personally am not going to use the banner system that is built in and probably quite a bit of others will not use it either. I had to add your link manually into my footer so that your link was still there since I have not purchased any brand free option. Here is what I had to do to add the same info that you had for the links...
open packages/shop/includes/footer.php
FIND:
Code:
?>
<?php
if ($banner = tep_banner_exists('dynamic', '468x50')) {
?>
And change to:
Code:
?>
<br>
<table border="0" width="100%" cellspacing="0" cellpadding="0">
<tr>
<td align="center" class="smallText"><a href="http://www.itvault.com"> vB Osc Shopping Cart Pro v1.0.6 </a> Copyright © 2010 ITVault Solutions (<a href="http://www.oscommerce.com">osCommerce 2.2</a> Integrated)</td>
</tr>
</table>
<?php
if ($banner = tep_banner_exists('dynamic', '468x50')) {
?>
That adds the footer links back into the script. you guys might want to set this where it cannot be removed just by deleting the banner.
