Due to the fact that im running a linux-based server a lot of the images are not shown. This is due to the fact of a very simple missspelling of the image names. instead of SpiritOfKings, which is the correct and working name for the image, it is stated as Spiritofkings in the database.

The icon names when extracted from the WoW data files are named one way, and the game references them in another way (different case)

This is a known issue and is fixed for Roster 2.0 (which is currently in beta) and the image pack for 2.0
