Q:

CSS frustration: How to center floating images of different widths inside LI tags?

I'm working on a webpage that has a javascript image rotator, but it needs to be able to handle images of different sizes.
The code that I'm using as a base has a DIV outside floating LIs which contain the images, but no matter what I try I can't seem to get the images to all be centered.  The only one that's centered is the one that's the full 800px wide.
I have a feeling it's something to do with float, position, or display, but I've been messing around for hours with no luck.
Here's my site:
Here's where I borrowed the image rotator code from:

Thanks for any help you can provide!

This works as well (In Firefox and Safari, haven't tried IE). Save as a .html for an example.
