Problem with view icons and backdrop of MBC

[REDBONE 1]

When I enter in mode Music , the three icons Genre, favorites and playlists without image , where do I have to get the image to display ?

If I set the view as genre, leave all the icons without picture (the pictures I have stuck in Metada / Musicgenre ) and MBS are perfectly visible. Where do you take pictures the MBC ?
