Looking through that documentation on a web page to which the Help button in that option window redirects me. I assume that is the documentation to which you are referring. Would that be correct? Based on that documentation everything appears to be set optimally. I have to read through it a few times to make sure I have it right.
Is this where you disable the use of local files for cover art? The text field on the Cover Art > Local Files option page is to only define a path to point the program when the below box is check, correct?
I think that I know what has happened. The first initial runs ran correctly. Subsequent run introduced the rogue cover art. I searched for all *.MP3 files in a finished directory and subdirectories. Then, I copied them to a single rework directory, no subdirectories. Just before reprocessing them, I intentionally or unintentionally played one of the files in WMP. Windows Media Player has a bad habit of taking the cover art from whatever file you play and puts two size images at the same single directory level were all the MP3 were ready to reprocess. Files names are always AlbumArtSmall.jpg and Folder.jpg. If MBP’s Cover Art Providers > Local Files option is checked, then that is why I have the same rogue cover art for all 924 songs. I need to find a way to stop WMP from doing that if I intend to keep it installed. That is very very annoying and tempted to uninstall it for good.
I used MP3Tag to remove all of the embedded rogue cover art. Selected them all and right clicked on the cover art display, selected Remove cover.
Have to assume that is one way to remove the wrong cover art. Also, have to assume I have no choice but to have MBP reprocess the MP3s to restore and embed the correct cover art.
Any other suggestions on fixing this, now that we know how this issue came to be?
