Change Kindle book cover graphic?
I have a Kindle book whose displayed cover art is just a bunch of dots. ("A Good Hanging", by Ian Rankin, FYI.) I'd like to - for no good reason, really - replace that graphic with one that I found at Amazon for that same book.
Is there any way to "edit" a Kindle book to change a graphic? If not, how about free .mobi books?
There's no real need for this, as I said, but I'm just curious.
