I must admit, that the widget functionality of the wp-banner plugin works slightly different from other WP-widgets. And after some guys mentioned that the wp-banner plugin using as a widget isn’t self-explanatory I will give you here a short howto.

Before you can put your advert into a widget, you have to make all the configuration in the Posts > Banner Admin menu. After you have put all the parameters needed, you can choose where to put the ad, into a own <div> or into a widget.

After you have chosen widget and saved the configuration you can go to the Appearance > Widgets menu where you can place the banner widget the usual way. No further options are needed. :-)
