How to generate cover thumbnails?
I'm in the process of formatting and reuploading all of my library to one of my old Kobos (a Glo HD), so I can use it as a spare whenever I don't want to take my Libra 2 outside the house.

As I'm doing so I'm wondering: is there a way to generate the book cover thumbnails (i.e. the ones that appear in the menu, homepage etc.) directly with Calibre? I have thousands of books, and navigating everything is going to be slow until Nickel generates all of the thumbnails, which as far as I know will not happen unless I manually go from page to page and wait until it's done. I looked at the KoboUtilities plugin but I'm not sure if the 'Upload cover...' option applies only to the main cover or not?

The Upload cover options uploads the set of images.

I think the Kobo driver already generates thumbnails when you send books to the Kobo?

Thank you, that was easier than I thought

@sherman it doesn't AFAIK the driver sends over only one cover 'size' and then Nickel generates the others, including those shown while navigating through the menu.
