OpenXservices

Question:
How do create toggling of banners using a single invocation code?
Answer:
n openx (or any other ad server), an invocation code will display only a single banner, but by using this mod, you can display two banners in one zone.
This mod will create a new invocation code, which the publisher needs to paste in his page.
When the page is requested by the user, banners will be displayed one by one, after few seconds (time will be set by the Administrator). The invocation code will change the banners automatically.
The administrator can set time for which a single banner should be displayed.
The probability of clicking the banner by the user will increase, which is an advantage for the publisher and the administrator.
You can also set the time of toggling of each banners.
