Whn i am in Video, .jpg files also are shown?

Putting a “dot” in the front of the name has special significance to linux / unix systems; they become Hidden Files.

The WDTV’s will be able to display them as thumbnails, because when the WD looks for thumbs, it looks for hidden files, too.

But they won’t be duplicated, because that’s a different process in the browser listing that does NOT include hidden files in the media listing.
