[Plugin: WP Bannerize] Alternate image instead of show all

I use the following code to show random banners but only one at a time:

<?php if(function_exists( 'wp_bannerize' )) wp_bannerize('group=bottomsponsor&limit=1&random=1'); ?>

limit=1 prevents showing two banners in the same spot. Using Random will alternate them in that one spot but having only two different banners makes you click a lot before you can tell it works. 5 out of 10 for each but sometimes four in a row sho the same one.

Great plugin by the way; I only found it yesterday!!!
