It's passed by reference unless you use the duplicate() call:
imageB = imageA.duplicate() -- explicit copy made; mem usage doubled
imaceC = imageA -- imageA is passed by reference; mem usage unaffected
This is a sure way to get nailed -- I mean not using duplicate --
because if (for instance) you set up some code that gets MIAW images in
series to send to a printer, and you do *not* use the duplicate call
for each MIAW, Director will not release those MIAWs no matter how many
times you send close and forget calls until the object doing the
calling is itself discarded.
That is the voice of painful experience. Try doing that with 80+ MIAWs,
all at 800 by 600, on a system with a mere 256 Mb RAM.
