Thumbnail preview with .FLAC files

[monigote]

Hello, I'm new to this forums.

I have this issue:

Usually audio files are shown with a thumbnail of the cover art when browsing on Windows Explorer:





but when I see .flac files this doesn't happen, and all I get is this:




I embedded the cover art in all the files' ID3 tags, but while the mp3 files have their cover displayed, the flac files are not.

What can I do to get Explorer to display the thumbnails?

Thanks in advance.
