The thought behind is reducing document size and maybe prevent problems while editing. Also the FODT (uncompressed, single file XML) version would become easier to handle or convert.
How is it possible to revert/und the Edit/Links, break command?
Best would be to have the dialogue almost the same.
possible starting points:
- right click on image, save as
- right click on image, replace and activate the link option
Just that would be more handy to do for all pictures in document at once.
