The css code mentioned above centered everything but putting the class in the sheet ripped the images apart and killed the rotating effect. That sounded violent. Must ban CSS!
Anyway, if I could figure out how to use the helpful class=center code above, with the rotator script I might be good to go.
Are you setting the margins?
In Safari, the large image appears to be off to the right. There is also a background image, so maybe that is throwing things off?
