Is there any chance that browsers in the future can be made to accept some
kind of overlay markup, specifying that two or more transparent GIF images of
the same size and shape should be displayed one on top of another as one
inline image?
It would also be nice to have a similar syntax that specifies that the first
image should be displayed by itself, and a control should be inserted next to
it that flips to the next image. This would be useful for flipping between
visible and infrared in an orbital image, skeleton and muscle in an anatomy
drawing, and so on. I'm not suggesting inline MPEG capability (which would
soon tempt every organization to have a flying logo on its home page). Each
frame would be a separate file (probably GIF), and the second frame need only
be downloaded if the user requests it.
