Actually, it *should* be possible to use a global cache of image data.
When an image needs to be loaded during the parse stage, POV can check
whether or not the image is already in the cache.  If it is, then check
the timestamp on the physical file.  If the image is not in the cache,
or the timestamp is newer than the image in the cache (would happen if
you use the output of one frame when rendering the next), then load the
image from disk... otherwise, use the image in the cache.
