I Agree, it sounds reasonable. I have prepared a new
changeset for this. Have some final testing to do before sending it.
Biggest problem why I didn't fix this in first change was that the
IMAGE_CMD func seems to behave a little different then I thought. I had
problems to use some functionality and expand variables in some
situations, but I think I figured out a way forward... 

Regards Petter
