Thanks Turing. I was able to work around, or figure a solution. First I clear all non-importing files, except jpeg, from the the digital directory of the album I am importing. Then I import. which usually comes in an unnamed album, unnamed author, in recent albums. I correct the album and author names, and set any global info I need, type of music, year, disc_ of _, etc., and artwork, then save. All changes are saved to each song. I then go to each song, and enter song number on disk, and any other comments, etc. If album cover does not automatically appear after closing/saving last song, I delete the entire album, and re-import. As all tags and other meta-data have been saved to each song by prior process, album cover imports and displays properly in grid. On occasion, it does not, but it has always been user error on my part, where I did not change some data on one or more songs, and it confuses iTunes, causing it to display the default "blank" icon. Correcting those entries usually makes the album cover display automatically upon closing the edit screen; on a few occasions I had to go through the delete and re-import the entire album, but all album covers are displaying properly now.
