Artwork issue

I use an iMac, and recorded some of my late mom's cassettes to the computer in mp3 format using garageband. I use a photo of each cassette for the artwork. No sooner do I update a couple of the latest recordings, I find the artwork has changed on its own to one of the other cassette/mp3's that would be in the same iTunes folder. I tried removing the album name from all the mp3's to blank, and use the artist name of "mom", thinking that the issue was they were in the same folder. I tried unclicking the option in iTunes preferences to auto import artwork. Rebooting is no help. The art for all my other multitudes of albums not related to this cassette to mp3 project are all fine. This issue is kicking my butt, any suggestions appreciated.
