Digging this up cos I find myself bugged by cover images that don't fill the screen. That is, when creating or editing an .epub, you can assign a cover image independent of the front/first/cover page.
THAT image fills the whole screen ... or at least, has the potential to if you get the aspect ratio correct - which is what I'm searching for.
Seems Kindle Preview doesn't do it properly so will have to test on the actual K3 ... wait one
