Problem with cover images

I would also suggest removing the file you attached since I am rather certain that the line in the book reading "Copyright © 2023 by Stephen King" is a pretty good indicator that it is still in copyright.

Already removed by Moderator, thanks
Yes, I found ASIN, it is at amazon pages under the book itself and it is editable by Calibre tools

fetch-ebook-metadata -p Amazon.com -a ´"$Author"´ -t ´"$Title" -o -c "$Author - $Title.jpg" > "$Author - $Title.opf" 
ebook-convert "$fname" "output//$Author//$Author - $Title.mobi" --from-opf="$Author - $Title.opf" --cover="$Author - $Title.jpg";

for example, or the same for azw3, it is really twice smaller ))
not always but in the most cases I get valid data

the main question how to force kindle to show that cover.jpg

as far as I understand identifiers:amazon=ASIN

fetch-ebook-metadata -t "Holly" -a "Stephen King" -p Amazon.com
Title               : Holly
Author(s)           : Stephen King & Justine Lupe & Simon && Schuster Audio
Rating              : 2.2
Identifiers         : amazon:B0BSXS2WNR
Comments            : <p><strong>#1</strong> New York Times <strong>Bestseller * A</strong> New York Times <strong>Notable Book * An NPR Best Book of the Year</strong>  </p>
<p><strong>Holly Gibney, one of Stephen King’s most compelling and resourceful characters, .......... from Stephen King.</p>

https://www.amazon.com/Audible-Holly/dp/B0BSXS2WNR
but that number refers to AUDIBLE AUDIO, not eBook

https://www.amazon.com/Holly-Stephen.../dp/B0BSRFPQXV
how to limit fetch-metadata to ebooks not audio?

[roddy20]

search returns 3 pages and the 1st is used, but we need the 2nd one
https://www.amazon.com/s?k=holly+stephen+king

something like
https://www.amazon.com/s?k=holly+stephen+king+kindle
will be better

maybe we need the format field in the search query?

The easiest way to limit the metadata to the ebook edition is to add the ASIN to the book's ID collection. Remember too that ASINs can be country/region specific but currently are always 10 characters. Since you appear to be using calibre to download the metadata, I would suggest combining getting metadata for one book at a time and using the mark 1 eyeball would be helpful to getting the correct metadata.

its OK but I need to do it manually for each book
I want a script to convert all the folder
BTW we have this option but it shows audio book (( both in Calibre GUI and in command line fetch

Thanks for your answers.
Now I have two problems
1 some books display cover images, some dont, format and conversion method are the same, where is the difference
2 I ll try to use ASIN if available, and Title+Author if not, then open Amazon page and confirm the correct data or search and enter manually, is it the correct way?

[roddy20]

I found two folders /system/thumbnails and /amazon bug with a lot of pictures in ***ASIN**.jpg format, it is related to cover images. Maybe someone has a detailed description what to do with those? Thanks

Now i m trying to get data three times, by ASIN, by isbn and by author+title, if there is a match, use it automatically, if not then review and select one of three opf files. It’s not perfect but seems to be working

The amazon-cover-bug folder is created by calibre and has thumbnails generated by calibre while /system/thumbnails is an Amazon folder. What calibre does is to copy the thumbnails from the amazon-cover-bug folder to the /system/thumbnails folder to replace thumbnails that Amazon modified/removed. This does not work on MTP connected Kindles where the /system directory is not made available.

my kindle has /system
it is like disk drive, not MTP
in some magical way I managed to add these covers to several books from the hundred
it is very strange because all those are in the same format (now AZW3) and with metadata including covers, ASIN and ISBN from amazon.com

[roddy20]

...and more, these images randomly appear and disappear after I connect kindle to wifi or USB, I cannot see any regularity ((

once your eBooks are done being scanned by your Kindle, plug your Kindle back into your calibre library so calibre can fix the covers. This will work for a PW5.
