How does BinaryImporter load textures?

Well I try to understand some parts of the Engine a bit more.

I know if I load a jme model it is textured as it should, however I fail to find out how.

Look at Texture.write().

if Texture.storeTexture is true, the image itself or else just the textureKey (location etc.) is stored.

To really see whats going on its best to debug such things.
