For changing the cover image in an azw3 file, most of the advice I've seen online says (1) use Calibre; (2) change the image in the Edit Metadata window; then to make the image show up, either (3a) do an azw3 to azw3 conversion or (3b) use the Polish Books function.

For me, both 3a and 3b generated a file that was almost double in size.
So question 1 is, is that normal?

But if I used Save to Disk instead, it generated a normal-size file that showed the new cover and seemed to work fine.
So question 2 is, is there some reason (which I didn't see in my quick check) why this would be a bad idea?

Thanks.
