Movie Art on Folders

I am trying to get movie art on all of my folders (large grid). The * *.metathumb works great on all my subfolders but not on the top one which is the local usb disk itself. The disk name shows up but not the art. I have tried putting a . jpg file in but that did not work either. What am I doing wrong?

You’re not doing anything wrong.  The WD is.

They don’t (yet?) support having a cover to represent a disk.   This only works for NAS shares at the moment.

you are talking about covers for the folder or moviesheets for folders?

Thanks, I guess they simply don’t allow what I was wanting.
