Library doesn't display updated cover

[Andy123]

Hi Folks!

I use Calibre 3.40.1 with Win10 x64.

I searched in the forum and manual for a solution, but found none. :-(

https://manual.calibre-ebook.com/edi...adding-a-cover

https://www.mobileread.com/forums/sh...ighlight=cover

The issue is

a) Calibre 3.40.1 does not import the cover of _some_ epubs, even though the covers are embedded (as cover.jpg in the epub itself)

b) If I add the cover via "Edit"-"Add A Cover"->'Save' and restart, I still can't see it in the library.

BUT: If I import the epub a second time, calibre's library shows the book cover in the second instance of the book.

Thanks for reading this! Maybe you have an idea!

I tested the 'repair ebooks' function in 'edit ebook' but it did not help.

Your old book did not have the cover properly defined. That requires 2 things to be flagged (semantics) in the OPF.
1)the image file (the name IS NOT the flag)
2)the (x)HTML file that uses the image AS the cover. (this file can NOT also be flagged as something else. Covers are seperate)

Using the Add cover tool does the flagging.

BUT (to your other problem)
Calibre Library only AUTOMATICALLY sets the cover SHOWN on ADD, not from a BOOK edit.

If you had opened the Metadata editor: Selected the format on the right: then click the brown book Icon (gets cover from format): OK
That forces a fresh cover to be used for the library. there is also an Icon for metadata.


Also note that Updating the Library metadata does not AUTOMATICALLY update the LIBRARY COPY of the book. (Books sent to devices by calibre, update on the fly, leaving the Library copy, pristine). To force the LIBRARY copy to update, you need to use one of the embedding tools like Polish

Thank you, 'theducks'!

You discribed this way and it worked instantly:
Edit metadata->edit metadata individually->click on 'epub' icon in the top right corner->click on blue book icon left of it->click 'ok'.
Now there is a cover in the library and also in the book details window.

Using the Add cover tool does the flagging.

This did not work (at least for me). 'Add cover' does not create cover.jpg in the folder, where the epub and opf files are. Weird.

But there is a complicated work around (at least for my case)
When I open 'Edit book' in a book with no cover in the library, i scroll on the left panel to the image with the tiny blue cover icon left to it. Then I open the context menu of the file and choose 'Export NAME_OF_FILE.jpg'. Next I look for the folder, where book's epub and opf are located and save the image as cover.jpg. Now do I close Calbre and when I open it again -voila- the cover is shown in the library.

This is only for the EDITOR to make the book correct. Once that 'edit' has been saved, the other step will work.
