There are no command line options in Mp3Tag for this purpose.
But MP3Tag is made to do mass-treatments like this with actions from the GUI.
For your purpose there exists an action type "Import cover from file".
What you have to do to use it depends on your folder structure and the names of the cover-files.
Hello -- I looked at this and it seems to work for each cd -- so I can fetch the cover on a per
cd -- but like I said, I have 70 of it there a way to create a loop so tht cd 1 get cover 1 -- etc up tp cd 70 gets cover 70 ?
This works for all CDs under certain circumstances.
How is your folder structure?
Do the cover-files lie in a folder with the music-files?
Do the names of the cover-files have a certain naming pattern, depending on tags?
