[Digikam-users] missing thumbnails - database cleanup???

[Gilles Caulier]

Hi Daniel,

Just to try, rename thumbnails-digikam.db database file and restart digiKam.

There is nothing important in this database. It store thumbnail with
wavelets compression. It's a cache.

You will need of course to rebuild thumbnails after.
