Can save cover graphic to wav file

[LyricsLover]

@roadstar

I wonder, is there any point in doing this?

Maybe this could be a reason:

Cover art saved to WAV isn't displayed in Groove

From wav you can convert to FLAC and stay lossless. Plus have the ability to tag and embed the album art. The mp3 format is lossy.

or

WAV Album Art doesn't appear in iTunes?

iTunes doesn't support reading cover art from WAV tags. I think you can add it from within iTunes, but then it's only part of iTunes' internal database. If you need a lossless codec to work along iTunes you could try ALAC or AIFF.
