Problem solved.
I gave up on ICACLS.EXE and went back to CACLS.EXE. I created an account to
give full control to so that I don't lose access to the files completely and
then I use CACLS to replace the current ACL and give my account and the
newly-created account access as follows::
CACLS Folder*.jpg /T /P Dale:R
CACLS Folder*.jpg /T /E /G AlbumArtAccount:F
Now I, and Windows Media Player when I am logged in, cannot delete or change
the album art but AlbumArtAccount, which never logs in normally, could log in
and delete or change the album art if necessary.
So I rip my files using iTunes to a different folder on the same drive, scan
and add my album art, set the permissions as described above, and then move
the files to the folders monitored by WMP. As long as I always remember to
follow all the steps, I'm fine.
I still keep my album art backed up separately just in case. Afterall, this
is WMP and as soon as the WMP product team finds a way to close this
loophole, they will.
