How could I save this cover in the Tag Editor in the album folder

[Biff]

How could I directly save / copy / download this cover (with a single click or key press or so) to the album folder(?):

What reason for? Why you don't want to save it file tags?

To let Aimp show it while playing the music of that album.

May be to save space on the drive. And I could watch the covers with other programs, file managers, image viewers, etc. And I don't know how to save a cover to all of the tracks of one album with a single click or so.
