Hi Minor thing and could be more of a windows question, but is it possible to change the pictures associated with the MP3’s?.. I can’t find anywhere in Engine Prime, or Windows>properties but must be imbedded as equally there is no IMAGE folder for these either…
A reload tags in Engine Prime as @yeltsin suggestested does not update all tags for tracks already part of the EP collection. Artwork is one of the tags that is not updated if its changed exeternally. (just checked again in EP 1.3.4 MacOS Catalina with an mp3).
Your only work around is
change the artwork with a tag editor
remove the the original track from the EP collection (you will lose cues, loops and analysis!)
add the track again to EP
The problem of the reload tags no longer working was introduced with version 1.3.1 of EP. I demonstrated it almost a year ago here: https://youtu.be/18C9MiuTMbk
