Do audio files have to embedded art for Dolphin to preview thumbnails? Can it use an image it found in the same folder as audio files? If not, then this doesn't count as a bug I guess but I'd prefer if this could have been included as a feature in Dolphin in the future.

If your audio file has an embedded cover art image, Dolphin will use it as the preview thumbnail.

If your audio file does not have an embedded cover art image, Dolphin will not show any preview thumbnail, even if you have a cover.jpg or folder.jpg in the same directory.

I see, I appreciate the fast answer. Is there any way this could be added to Dolphin?

> Do audio files have to embedded art for Dolphin to preview thumbnails?
Yep. The thumbnailer currently reads the file itself.

> Can it use an image it found in the same folder as audio files?
Nope. :)

Seems like a reasonable request!

The folder thumbnailers goes hunting for a TS_VIDEO folder (remember DVDs) so I guess it's not unreasonable to go looking for a cover file too

Ah I think I misread it. So you basically want all audio files in the same folder (that don’t have a embedded cover) to have the one from a cover.jpg inside the same folder?
