This allows OpenX ADs to be delivered directly into the top (left or right) of Joomla content (no need to use tag). Use OpenX AD system to control how and when ADs appear (contextual, URL based) in concurrence with the plug-in parameters you set.

This has the same features as the OpenX Article Module with two additional parameters:

• Choose AD to appear LEFT or RIGHT at the top of content
  
• Choose not to have the plug in active by setting category ID (comma separate for multiple) to not have them appear in un-catagorized pages set to 0

After installing, publish plug-in, choose your parameter options and add your OpenX Ad system settings.
