Hi Marc,

I was just curious to try to increase the size of one of my images too, I
have just used dd and succeeded with not much problems.
My image was 500Mo with win98 on it, resized to 1Go with  
dd if=/dev/zero of=win98.dsk seek=1024000 count=1024000.
Boot: ok
Dos Fdisk can add a new partition on the newly created non allocated space.

Additionally, for Linux guest operating systems, if you grow the underlying 
partition for the existing filesystem you may be able to extend the existing 
filesystem to seamlessly use the extra space.

Make sure you give a seek value that corresponds to the end of your virtual 
disk, otherwise you'll wipe some data...  If you have the space you could 
also consider making a backup of the original before playing with 
resizing ;-)
