Thought I'd make a new post. :-)

Somehow, the Compress Images in Polish Books works different than the utility in Edit Book.

Using the one in Polish Books, I get this output (on all images with different names):
f01-02_fmt.jpeg could not be further compressed


Using the one in Edit Book I get this output (on all images with different names, different compression ratio but all get compressed):
f01-02_fmt.jpeg compressed from 27.5 KB to 11 KB bytes [59.9% reduction]
