Anyone know of one?

As an alternative I might go the image overlay route here:

I also want my slideshow to load super fast without having to load all the images that will go into the slideshow when the page loads. Instead I want it to download the first one … render the page and let the user get on with things… then have the slideshow pull in the images dynamically.  I found this solution with JCycle ( jquery )
