This looks like a great feature.

For sh*ts and g*ggl*s I tried to create my own book. I imported a picture and tried to make it the cover and got the following message:

I was able to get it all sorted out by putting a new cover in in Calibre, polishing the book to get it inserted. But somewhat cumbersome... Maybe there is a better way???
