Actually, I just discovered that the CTDB plugin in EAC makes it easy to obtain album art when using CTDB for obtaining metadata, and I will probably utilize this feature instead of scanning my own album art. EAC is set to automatically put a copy of the album art in the folder with the ripped tracks, so I will probably utilize this feature. But since I no longer want album art embedded in each ripped track, I have removed those commands from my FLAC arguments.
Here are my current (and hopefully final) FLAC arguments:
-8 -V %source% -T "ARTIST=%artist%" -T "TITLE=%title%" -T "ALBUM=%albumtitle%" -T "DATE=%year%" -T "TRACKNUMBER=%tracknr%" -T "TOTALTRACKS=%numtracks%" -T "DISCNUMBER=%cdnumber%" -T "TOTALDISCS=%totalcds%" -T "GENRE=%genre%" -T "ALBUM ARTIST=%albumartist%" -T "ALBUMARTIST=%albumartist%" -T "COMPOSER=%composer%" -T "COMMENT=CRC: %trackcrc%" %haslyrics%--tag-from-file="LYRICS=%lyricsfile%"%haslyrics%
