Clearly, KindleGen is reprocessing the images. But what's going on here and does anyone know how to suppress the reprocessing?
A does not equal B.
The difference in final file size is mainly due to the fact that the final file contains the entire ebook in the older MOBI format ... and
the entire ebook in the newer KF8 format ... and
the original source files from which the ebook was built.
