From time to time I need for different reasons (eg wrong cover, dislike it etc) to remove a cover from all songs in an album. It would be practical to have the counterpart of "set image 4 all" named: remove image from all or something. Clicking this button will remove a cover from all songs in the songlist from where I edited a song.

I see what you mean.. hmm... So far i've gone as far as "creating" my own album covers, by using a picture of the artist or the band where i couldn't find the right album cover. I'm not proud of it, but i find that everything is better than a blank cover... perhaps i should make a "default" cover that looks good. White label?
