The image (cover.jpg) is in folder with mp3 files:

$ ls Música/Lana\ Del\ Rey/Honeymoon/
01 - Honeymoon.mp3               06 - Freak.mp3                     11 - The Blackest Day.mp3

...but beet thumbnails doesn't find it:

File being present in the folder isn't enough for beets to know there's album art there; the art needs to be associated with the album in the database. You can do this with fetchart.

You can also check whether an album has associated art with:

beet ls -af '$artpath' QUERY

[sampsyo]

Please reopen if you're still having trouble.

The problem is embedartwith remove_art_file: yes, it deletes the album cover before it executes thumbnails plugin:

If I suppress remove_art_file: yes option it works, but I don't want to keep the cover images.

[sampsyo]

Thanks for doing the investigation! That definitely seems like a problem we should solve.

[simonbcn]

The problem still exists.
Moreover if I run beet thumbnails it tries to use image files that aren't:
