So there are two jpg files in the same folder as the tracks. There's also a Covers folder which contains a pdf. Which or all are you interested in importing?

Might be worth noting that I can easily remove all of that extra stuff & just leave the one JPG if it makes a difference.

Turns out because your pattern is so specific that I could do it in one line. From what I can see the only requirement is a jpg image where the filename contains an 'a'. The primary name can't contain an 'a' 🙂

Download the action at:

https://2manyrobots.com/actions/ExtractSpecificArtworkfromFolder.zip

Drag the zip file into the main window's file list area. You'll now have an action named Extract Specific Artwork from Folder. You can run the action via Actions>User Defined>Extract Specific Artwork from Folder.

Load all the files in the box set or simply one disc. Select all files ... or at a minimum all files from one disc. Try it first with one disc. Run the action.

A few points which can be changed if you so wish:

- older artwork in the files is not removed.
- if you specified maximum image dimensions in Preferences-Artwork, the imported images will be scaled down if necessary.
- the files are not saved. You can have a look at the results of the import.
- if you want to save the files do a Save.
- if you do not want to save the files, do a File>Revert

Let me know how it goes or if you need anything changed.
