I'm working at a script to rotate banners so I've colected some for rotation. It will be a nice colection of things one day. Most banner exchange programs don't allow scripts to mess with their code but pretty often you can promote the referral link for the same credit or even more.
As this is just a link not a tracked advertisement it can be hidden moved or injected along with other scripts happening on the page, "pay for preformance" offers the webmaster much more freedom to promote.
On the categories blog I've made it so that clicking a category displays a new banner. Because of the coolness of my script the page doesn't reload. I can make it reload before a category is displayed but that would spoil the whole script, it's great the way it is.
So I need banners that I'm allowed to rotate if a thing is clicked, new adverts should spawn withouth reloading the whole page in my opinion.
humm, now I figure 20 sec is more as enough? Lets try and make that $_$
