only u need to change the mayus caps to your website: HTTP://WWW.YOURWEBSITE.COM/DETAIL.PHP?ID=
and upload your pics at your layout_images folder.
then, u put this code in some part of your detail.tpl, (to my preference, i was put it below od the description on each ad).
<tr>
<td colspan="2">{$ad_description}</td>
</tr>
<!-- make this new column-row -->
<tr>
<td colspan="2">HERE PUT YOUR CODE OF SOCIAL BOOKMARKS!!</td>
</tr>
<!-- make this new column-row -->
if u want more social bookmarks code, u can check here:
