I don't have time to test this, but here's a start: From a previous post I am assuming that you are ripping to FLAC image with FLAC and MP3 tracks.
In your REACT.ini ensure the settings below:
[Settings]
...
ImageExt=flac
RunCoverDownloader=0
...
[UserTrackFormats]
Flac=1
Wavpack=0
LameMP3=1
NeroAac=0
iTunesAac=0
OggEnc2=0
...
[UserSettings]
...
EmbedCover=1
...
In your config (REACT-image.cfg), presuming it has not been edited previously, on line 49 you will see:
IF EXIST "@cover@" (
SET have_cover=1
SET embed_cover=@EmbedCover@
)
Change that code to:
SET cover = C:\My Documents\Catraxx\Cover Art\$cdartist$ - $album$.jpg
IF EXIST "%cover%" (
SET have_cover=1
SET embed_cover=@EmbedCover@
) ELSE (
ECHO.
ECHO WARNING: '%cover%' does not exist!
ECHO.
)
Then, find and replace any instance of the text "@cover@" in the subsequent code with "%artist%". E.g. on line 108, change:
IF %embed_cover%==1 SET Cover_tag=--picture="|image/jpeg|||@cover@"
... to:
IF %embed_cover%==1 SET Cover_tag=--picture="|image/jpeg|||%cover%"
Pay particular attention to lines 108, 150 and 180.
