I'm not sure if anyone else has ever posted something like this. I have always been frustrated at being limited to one banner image to encompass all the things that interest me. Because of this, when I was revamping my LJ the other day, I decided to see if I could get it to randomly display a banner on each page load from a select group of banners I had created.
I found a way and have put it into a five step process for anyone to use.
