 I am running Mathematica 4.01 on G4 cube under MacOS 9.04 and do not have
your problem. In particular the example you quote looks exactly as it should
so the problem must be specific to your particular setup and not a
Mathematica 4 on G4 problem, as you describe it.

As for you second question: I think the most reliable approach is to paste
the image, use the "Convert To" submenu in the "Cell" menu to convert it to
InputForm and then evaluate it again on the other platform. I use this a lot
and it works without a glitch, at least for relatively simple images (I have
not tried it with very huge ones).
