Hi , I want to add an image in background music instead of visualization. How can I do that?

Do you mean artist fanart? see http://kodi.wiki/view/Music_artwork#Fanart-_Artist

not necessarily a fanart artist, I want to put any default picture instead of choosing a visualization. it's always the same way?
