It would be simpler to copy image files after they are written. But I don't
this the issue was to copy image files locally. The original poster wanted to
update third-party images by shipping fileIns to a reference image instead of
the whole image itself. The poser, then, is how to verify that the resulting
image is same as intended.
I would simply use xdelta (see xdelta.org) for situations like this. E.g.
xdelta delta ref.image thirdparty.image thirdparty.xd
and ship thirdparty.xd
xdelta patch thirdparty.xd ref.image thirdparty.image
The downside is xdelta is a memory hungry utility. How big is the image?
