If I have a disk image that is 600MB is it possible to split it into two parts of 300MB? Can Disk Utility do this or is there another free program that does this?

you can split it but then you have to join the two before mounting.
To split a file called file1.dmg(of 600 mb) into 300mb parts, open the terminal and write
split -b 300m file1.dmg fileNew

This would split it in two parts called fileNewaa and fileNewab.

Then to join the two parts, write
cat fileNewaa fileNewab > fileNew.dmg

This would join the two in one file again called fileNew.dmg

cheers

There used to be a GUI utility for this called DMGscissor - sadly, it seems to have completely disappeared. It was maintained by a .Mac member - I wonder what happened to it.

Oh well, guess I'll have to use the Terminal for now, like abhishekit suggested.
