Thumbnails in Orbiter

[Bodyhat]

Ok I've been researching this and have read some helpful posts but while trying to get my pictures to display thumbnails in the orbiter I noticed a couple of things.

Within the pictures folder LMCE creates two additional files for each picture. One is .id3 which im guessing is for the database. Then a thumbnail under the file ext of .tnj.

I had to manually copy each picture and rename them with the .tnj extension within Dolphin (linux explorer) in order to display the thumbnails. Problem solved but unpractical if you have a large collection of pictures to transfer. But I did notice that a couple of pictures didn't have a .id3 copy. So i thought the file name was the issue so i changed one file name by removing all the spaces and it generated a .tnj by itself!

So my question is...does the file name have to be a certain format in order for linux to automatically generate a .tnj file? Or am i doing something wrong?
