	[DJW:]  Indirection would introduce extra round
	trip delays and complicate HTTP pipelining.  I 
	also feel that there is no reason to have a set
	of mock images, even if you go indirect; one could
	use LINK on the indirect page.

	Pipelining is already quite messy here, because you
	don't want to start requesting the images until the
	rest of the page loads, even though they appear first,
	and you want to pre-empt fetches if the user mouse-overs
	out of boredom, whilst waiting for the base versions
	of all the iamges to load.

[DJW:] Note that nothing here should be taken as 
encouragement for implementing buttons as images, or
for animating them; I like neither, I'm just trying
to consider, from a aminly academic point of view, the
most appropriate mapping of the function suggested onto
HTML.
