This doesn't do what I was describing. I apologise for being unclear.
The idea is that the jQuery module in this world doesn't get loaded until
it is needed. When the user hovers over the image, then the jQuery module
is loaded and used, but until then, nothing needs jQuery so it's not
loaded. (Or replace jQuery with whatever it is that's special to this
image; the precise library doesn't matter.)
