iWeb Gallery - Carousel is a memory hog!

I'm working on making a website with a .mac gallery and decided to publish some albums to try the new gallery functions. The only programs I had running were iWeb, Safari and iTunes. When I started the carousel view in the gallery, everything on my computer got bogged down and music from iTunes got really messed up. I checked activity monitor and my usage was at 91% compared to about 50% when running a page other then gallery with carousel.

I didn't think anything running in Safari could take this much memory. Anyone else notice this or had complaints from people who view their galleries online?
