locking the images of items inside a media library

[DR-BrightClone2]

i like to use a subdirectory instead of a playlist for my playlist i like to use a custom image for it and  before 10.9 the custom image i uploaded for it  stayed there until i scanned my libraries then i would need to reupload my custom image but after 10.9 every so often the image changes itself to the cover art of one of the songs in the directory. how do i lock the image so it doesnt change unless i change it

You could try saving it locally in the sub folder and naming it folder.jpg (I think).
