Hi Linux_da,
the Basic skin folder is very important, as it is the fallback folder for all skins. If OrbiterGen can not find a graphic file for a skin, it tries to get it from Basic. I recommend watching _all_ screencast from tschak, as it is essential to understand the logic behind HA Designer and OrbiterGen. There are a lot of pitfalls in designing skins for LinuxMCE, watching the screencast avoids the most.
