There are several Jave scripts that will flash photos up for you but as others say its its not worth it.
I always bookmark the pages after the intro anyway ;)

I have always tried to keep my websites ad free but there is a new nasty now, web farming, where people webwhack your entire website, pepper it with google ads and then host it on there own servers.
They make money from your website! B*$t*7s!
