You might want to play with mod_expires to set expiration headers on
images.

Well, thanks to all the advice (and advisors), there are two workable
solutions.
For me, I'm liking the ease of display/maintenance for now. (Just wrap an

However, an arsenal of buttons (and the software to manage it) may be

browser to use a cached version of an GIF/JPG that's used for a rollover
effect?

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