Sven,
interpolation  works for 2D bitmaps as images as well as for density files.
Interpolation computes average values between pixels (for 2D images) and
voxels for density files.
You can forget density files for the moment, they are made for others uses.
For bitmaps, values 2 and 4 are valid (I suggest 4)



 image_map { jpeg "E:\Scripts\Eigene Bilder\Povray
Textures\Sphere_Earth_01.jpg" map_type 1 interpolate 4}
