That might a good function to have -- it's certainly better than simply
flushing the cache when you know you want to refresh a given image --
but it obviously doesn't solve quite the same problem.  A mode that
displays lots of images might like to be able to have them all update
auto-magically without having a bunch of elisp hair in place to keep
track of their status; the elisp solution would probably be clumsier and
less efficient than simply statting (periodically) upon redisplay.
