Cover problem when using Calibre's "Polish" function
I have a cover problem of a slightly different nature. When I use Calibre's "Polish" function, instead of epub/epub convert, to change a cover the book gets transferred to my Nook HD+ with no cover @ all. All looks well in Calibre & it looks like the cover was changed successfully. However, all I see in the device is a grey square - similar to what you see on some library books transferred through Overdrive. I use Calibre Companion to transfer my books & the cover does show up within the app - just not on the device bookshelf. Even when the book has a cover & I don't what to change it the cover does not transfer unless I epub/epub convert before sideloading This is a consistent problem, not a fluke. Does anyone have any idea why it is happening?
