But doesn't CopyMem use the blitter to move the memory?  If so, then you
CAN'T use it to move your image from FAST memory to CHIP.  You'll need to
have the CPU do the memory move, not the blitter.  There probably is a Manx 
library routine that does this (like movemem or something).

It should, provided you use the CPU to copy the memory instead of the blitter.

If I'm wrong about CopyMem using the blitter, then you can ignore this message.
