Well, thanks to all the advice (and advisors), there are two workable

For me, I'm liking the ease of display/maintenance for now. (Just wrap an

Thanks for the filter idea Keith. I'll try it out!

Thanks again!

Frank,
Thanks for the code snippet. However, I'm having a bit of trouble mapping

I really think this is a case where we might be trying to hard to be

The problem is actually in your scripting... The browser should be caching the image
after the first view anyway, but the problem you are referring to is a result of not
pre-loading the images. You do that by the following script when the page loads:
