In order to help pay for our drupal 6 website we need to be able to
derive some revenue from banner ads. I am looking for suggestions on
how to implement banner ads utilizing google type ads (or someone else)
so that the ads display within a predefined rectangle and if the users
clicks on an ad (which takes them to a new tab/page) it gives our
company some revenue.
