[Thumbnail] Associate a Thumbnail Album To a Music File.
1) Metadatas
It is possible to embed an image in the metadata of a file (FLAC or MP3 for example). To do this, use an audio file management software.
2) External image
Place an image in the folder that contains the different music tracks, and rename this image: "folder.jpg".
If the audio file does not have a metadata image, this one will be displayed.
