Can Importing Cover Art from PC be Done?

I was curious if import cover art from my PC could be done rather than Discogs & MusicBrainz. Thanks.

See the tag panel and right-click on the picture area. There are many functions for pictures.
Alternatively, use the extended tags dialogue (Alt-T).
Or create an action of the type "Import cover from file"
So many ways to do it.

thanks - I was looking in tag sources.
