Hello,

A technical question from someone who has no idea what he's doing. :-) I'm trying to exact a thumbnail directly from the thumbnails-digikam.db database, but this command gives me a file that is not recognized as JPEG:

sqlite thumbnails-digikam.db "SELECT writefile('thumbnail.jpg', data) FROM Thumbnails WHERE id=1;"

What am I doing wrong?

Thank you!

Kind regards,
Dmitri
