In Options, for the File Browser, add |noaad.txt to the end of the "Specify path to find images" box. That will then ensure that any album which has that file present in the folder will count as already having album art.

If you really want to do it by artist, then you could add |..\noaad.txt too. Then it will match if there is nooad.txt in the album folder, or in the parent folder of the album folder (which in your case, is the artist folder)
