As the thread slipped into private communication, here is the solution for 
using metadata in BQM to keep image history.

Since the BQM, like the image editor, always encodes a new image, but this is 
not desired if only metadata is applied, there is a special feature in the 
BQM. Always put metadata tools at the end of the tool list. Then it also works 
in your case with the image history.
