banner after first post on each page

[bucks]

I have modified my forum to show a banner after the first post on each thread ( see below )

http://www.e30owners.com/forums/show...1921#post41921

What i want to do now is have the ad showing after the top post on every other page ie. if a thread is 4 pages long then the ad just shows after the first post on the first page, i want the ad to show after the first post on each page, hope that makes sense ?

Any idea how to do this ?

Thanks.

use the built in ad location template for after first reply?
