Removing them proves issues. Depending on the editing it may not be possible to get a clean-edge. This was a major problem when we tried it on the One Piece wikia, forcing us to only use LQ stills and cuts from the anime/manga. So avoid problems, its always been better to use the art as the companies have released them. :-?

In short, it cannot always be helped. These images are normally fine though, as their released to the general public and are within the public domain. We can use them so long as its within reason.
