Here is the php code I use for displaying random banners in my forums. I use it in my global template and just place $random_banner[$random_number] where you want the banner images to appear. This is tested on IPB 3 with images only and not 3rd party delivery methods such as Adsense

 

<php>$random_number = rand(1, 5);

$random_banner[1] = '<a href="link"><img src="img" alt="img alt" border="0" /></a>';
$random_banner[2] = '<a href="link"><img src="img" alt="img alt" border="0" /></a>';
$random_banner[3] = '<a href="link"><img src="img" alt="img alt" border="0" /></a>';
$random_banner[4] = '<a href="link"><img src="img" alt="img alt" border="0" /></a>';
$random_banner[5] = '<a href="link"><img src="img" alt="img alt" border="0" /></a>';
</php>


$random_banner[$random_number]

Thank you John. Can you show the ads just after first post?

Thanks John. That is some useful code.

I use oiopublisher (aff link hope you guys dont mind) to place my banners plus i can geo-target and sale banner slots if i want while i sleep.
