I don't think ffmpeg knows how to read cover art from MP4 files, so it 
won't be copied.  However, it is possible to use ffmpeg to add cover art 
to the MP3 file after conversion if, e.g., you've downloaded the 
programme thumbnail with get_iplayer.  The audio data is just re-muxed 
when then artwork is added, so it's quick.  However, I don't see how 
that process could be automated with WinFF since it doesn't support any 
variable substitutions in the ffmpeg command lines it generates.
