PHP based image rotator:
Pro's = Will always work no matter what browser or hand held device you're on on whatever OS.
Con's = It's server side so it won't be as fast as a client side language like JavaScript, naturally.

JavaScript based image rotator:
Pro's = It's client side, so it's pretty fast.
Con's = JavaScript can be very easily turned off from within the browser settings so there's no 100% guarantee that it will work for everyone.

Take your pick.

Directions are at the top, in the comments but if you have problems with it, let me know.




If you do use a JavaScript image rotator, consider the <noscript> tag.
