Display embedded FLAC album covers in Nemo

[ArRi2969]

Currently, Nemo displays thumbnails for MP3 files that contain embedded album artwork. However, embedded album covers stored inside FLAC files are not displayed as thumbnails.

Many users organize their music collections in FLAC format, where album artwork is commonly embedded in the metadata. Other desktop environments and file managers (for example KDE Dolphin and some XFCE configurations) are able to display these embedded covers.

It would be useful if Nemo could generate thumbnails from embedded FLAC album artwork in the same way it already does for MP3 files.

Benefits:

Better visual navigation of music collections.
Consistent behavior between MP3 and FLAC files.
Improved user experience for users with lossless audio libraries.

Thank you for considering this feature.

Hmm.. you can add custom thumbnails, but I don't know if this applies to FLAC files as well.
Check out this tuto to learn how to apply custom thumbnails:
