Bitmaps/Images are maintained essentially the same way in
the two releases: stored as data on the same machine as the
display.  I don't understand why you think balloc() and
allocimage() behave differently with respect to storage.

The libraries are very different, however, so you may think
it's behaving differently.  It sounds like what you're asking
for is the routine loadimage(), described in allocimage(2).
Let me know if that doesn't solve your problem.
