Rotating headers on Blogger

Hello all!  

It's been a while since I've been on here, but I was wondering:  are there any Blogger users out there that know where or how to make your header rotate images?  I know that there's a complicated code often used on Wordpress, so there must be some equivalent on Blogger. 

If anyone knows, I would appreciate the help!  I'd like to make my blog a lil' more spiffy :)
