Any way to extract jpegs of the book covers?
I wanted to make a screen saver of tiles where each tile is a cover of a book from Calibre.

Is there a way to automatically generate jpegs of all my book covers?

The Save to Disk Preferences has a checkbox to save the covers as separate files, they get the template name - e.g. {authors} - {title}.jpg. But IIRC you have to save a format file too, which you can delete en-masse easy enough.

Calibre stores the cover separately in the library. Each directory will have a cover.jpg file. You could iterate over the directory structure to read them.

... or do a search for *.jpg in the calibre library folder and copy the jpgs to some other place for further processing.

Even better could be if the screen saver start by looking for a calibre library and automatically read the jpgs from there. Only read, never write. It could also prioritize newer books.

The only prob with that is they are all called cover.jpeg. Your script must change the name as part of the copy

Oops!

cover.jpeg it is...

My only excuse is that I treat the calibre libraries as black boxes and avoid even looking inside them.
