Hi.

I know what I'm about to suggest isn't exactly what your looking for... 
but have you ever considered using a flash object?

Advantages:
- Less messing around with JavaScript and such, easier to deal with.
- Makes it harder for visitors to grab images from your client (if like 
most clients I know, they're pedantic about such things).
- As long as flash player is installed, it should run exactly the same 
on every browser.
- It all loads at once and no delay is formed between fades.

Disadvantages:
- Harder to edit if you need to add another image to your collection.
- Takes longer to load on slower connections.
- Won't load at all in IE if active objects have been disabled in the 
users security preferences.

The pros and cons are pretty much head at head, so it really boils down 
to a matter of personal opinion... but I thought I'd just point out the 
option. :)
