Thanks Lowlander.
I think that is wrong logic based on a bad assumption. Now I've made a dummy image and saved it to all tracks that didn't have proper artwork.
MM, Options, Library has a whole section on metadata lookup. It even allows you to specify the permitted sources for lookup. When background metadata lookup is NOT ticked, it should not do it - anywhere. When it is permitted, include 'other tracks in same album' as a viable source.

That's it. MediaMonkey will show Artwork from another file on the Album if the track has no Artwork.

I search 'more from same album' on track A. It yields tracks A, B, C, D. Tracks B, C, D show their own correct art (stored in tag). Track A's art is wrongly copied from Track B and is an 'unsaved image'.

My use of the 'Album' field might contribute to this, but I can't see how. I enjoy a chocolate regardless of it being served alone or from a variety pack. I don't care what album a track was packed with. Album is anathema to me. But the field displays on many players including my LG TV media player. I use the MM album field like 'zz,1991,Soundtrack', or 'de,1967', or 'en,2008'. When that info scrolls across my Honda screen I know immediately what language they are singing in (zz = instrumental) and when the song was released.

The example we are using (A,B,C,D) above has the album 'zz,1991,Soundtrack'. It found four tracks in that 'album'. Three of them have correct artwork 'stored in tag', but the track without any artwork was populated from one of the other tracks. Not from a folder, but from artwork stored in a tag. That is wrong.

I just saved a new track with OSB, converted to FLAC with a batch, and put it in MM. It immediately chose (wrong) artwork for it from another track with the same 'album' info.

Yes, I know that is not what you designed 'album' for, but it works perfectly for all my needs, and should not be even considering to look elsewhere to fill an empty field. If I have no artwork I want that field left empty.

Right click on the track with the wrong Art and do Find More from Same > Album. Does the track which Artwork is shown also show on this Album?

My first post, but with a problem that has bugged me for years. I did extensive search but found no other thread on this issue.

The wrong artwork displays on about 10% of my tracks. I never do any metadata lookup (not for title, artist, artwork, lyrics, etc) and have switched that off everywhere I can find. I 'save image to tag' and never to folder. I've searched in my single music "Collection" folder, and see no jpg files. On my main screen, below the playlist on the right side is where I can choose to display the artwork for the "Selected" track, or the "Playing" track (or Visualization). I have chosen "Selected". Now I select a track (Sweetest of All by Dr Hook). The display on bottom right shows wrong artwork (G'day, G'day by Slim Dusty). That's wrong. I do have that song on a different track, with that artwork, but it is wrong to appear when Dr Hook is selected. Properties on Sweetest of All, the Artwork tab shows no artwork. That is correct, as I've not previously saved anything there. Why is Slim Dusty making an uninvited appearance?

"Files to Edit / Inconsistent Artwork" is useless to me as I don't necessarily want the same artwork for different tracks (even if from the same artist or album). But "Files to Edit / Unknown Artwork" shows only 300 tracks, some without artwork (as I would expect, some with wrong artwork (ie from other tracks in my collection). In these cases, Properties does show the wrong image, but "Unsaved image". Icons then allow me to delete it or to save it. Image location can be 'to tag, else to folder', 'to folder', or 'to tag and folder'. I really wish there was a default option of 'to tag if possible, but never to folder'.

The wrong images are correctly in the 'system' but for other songs. I don't have any images that appear to be automatically downloaded. So the problem seems to be in the database. Corruption? What to click to flush out the images that I didn't specifically save to the tag of a track?

What causes this, and how to fix it?
