Each folder has its own cover art. The cover art files are all named either cover.jpg or folder.jpg.
Is the answer found in the above thread still correct? Or has a way been developed since then to streamline this process? I have approximately 3,000 albums.
If the pictures are already there, then there is hope to automate the process:
Load all the files.
Select the files.
Open an Action (Quick) of the type "Import cover from file"
This will import the file folder.jpg if found in the folder of the current file.
You can then filter for the files that have not yet got a picture:
and then apply the same type of action only this time
Press F3 2x to see how many files are left without cover and then start the action a 3rd time, this time with
which will import the first found jpg from the current folder.
The filter is the input are at the very bottom of the window.
Press F3 a couple of times to see where the filter gets hidden or displayed.
There you enter %_covers% MISSING
That should reduce the number of loaded files to just those that have no cover.
And only those need treatment in the next round.
