-        Number of level which the fanart of a media file can be propagated upwards.
+        This setting allows to increase the number of levels which the fanart of a media file can be propagated upwards (examples refer to basic layout /Root/Audio/Artist/Album/song).
+        A value of 1 adds the fanart only to the direct parent container when a media file is added (e.g. the Album container).
+        A value of 2 means you propagate that image to the parent container as well (e.g. the Artist container).

+        Depending on the virtual layout propagating thumbnails can reach containers like Video or Audio. This settings forces a minimal depth for propagation to apply.
+        It is setting the minimum number of path elements for container using fanart from media files (e.g. /Root/Audio/Artist has level 3 so the image can be set).
