fanart.jpg support when browsing folder

Hello,

When I browse folders (not in the library but the folders itself), if I create a folder.jpg file the image get displayed as a thumbnail.
I was wondering if there is any way to get the same behaviour for fanart.jpg.
So if I create a fanart.jpg (or any other name) file I can have it displayed on the background on the fly.

I am not sure if this is linked to the Skin (but I guess so). I am using aeonmq 3.

Thanks and regards.
