Steve Kowalik 84b2ac45de Allow overwriting old images
The two duplicated functions, save_image and finish_image will move
an existing image out of the way if it exists, but it isn't
configurable. Check an environment variable is 0 before doing so.

Switch save_image to just calling finish_image, rather than
duplicating its code exactly.
