Thanks
cearp, works great!
Quick question: do you reckon this technique could be used to add a cover to any book, or is it just possible for KUAL?
I'm asking because since version 5.8.5, it hasn't been possible to have covers on AZW3 files downloaded through the Kindle cloud (the issue is summarized
here). Several people (myself included) would be very interested in a way to bring back covers for those books!
