Need a plugin to display different sets of rotating banners in specific forums. Example:
Banner1 & Banner2 in Forum7
Banner3, Banner4 & Banner5 in Forum13
The banners should appear after the first post in each tread in the specific forum.
I would appreciate any help provided. Thanks.

This could easily be done in a plugin, you just want to set banners to be displayed in certain forums?

Yes, different banners in different forums but couldn't find a suitable plugin that can do it.
