When I edit a music file in mp3 format, I insert an image with easytag. When I play the file, the multimedia player (vlc, rhythmbox, smplayer...) does show me the cover of the file that I inserted previously. However, in nautilus the covers don't appear, in KDE with Dolphin I don't have problems, with Cinnamon and nemo neither, it only happens in nautilus with Gnome Shell. Can someone tell me if I'm missing a file or something or how to fix the problem?
I did the following:
if as a result of executing this your thumbnails don't start appearing immediately, then try the following:
(This will kill the nautilus file manager, so then restart it by opening "files".)
If that does not work either, then try logging out and then back in.
