how do i add adsense to phpBB forums?

how do i ad adsense to my phpBB forum. and i know that you can add it to every page because i have seen other phpBB forums with it. my forum is in my signature link if you have never seen a phpBB forum before...

 

Where do you want the ads? Inline, header or footer?

 

header of every page kinda like this forum

 

ACP -> Styles -> Templates -> Edit -> Choose overall_header.html from the list.
Search:

		<!-- IF S_DISPLAY_SEARCH and not S_IN_SEARCH -->

Code (markup):

Add your AdSense code just before:

			<div id="search-box">

Code (markup):

Tell me if it worked.

 

Is this for phpBB2 or phpBB3?

 

phpBB3, as the forum in his signature runs phpBB3

 

checkout the phpbb forum help site, im pretty sure they will have mods for the forum that will be easy ad management.
