If it does exist, serve the already existing banner. Once the banners are all made server load is extremely low and should not be a problem even on a high traffic site.

I agree, but why bother with graphics? That banner, and actually banners that look a lot more interesting, can be easily done with an html table. That's how I'd do it...
