Windows 7: WMP12 downsizing album art when syncing

I apologise if this issue has already been discussed before - I have done extensive searching and can't find the issue or answer elsewhere.

My issue is with what WMP12 does with album art on mp3s when syncing to an MP3 player.

All of my album art is embedded in the mp3s as reasonably large jpgs but when I connect my Sony Walkman or Cowon J3 and sync the mp3s to the players, the album art shows up on the players as very small.



Is there a way to stop WMP12 downsizing the album art on syncing?

Thanks...
