That's because it was "applied head on". That's what "map_type 0"
means. What you need to do is use UV mapping (provided your model has
UV coordinates of course).

By default, POV puts the image in a 1 by 1 square from 0 to 1 on the
x and y axis (I think, not sure about the axis). You can scale,
translate and rotate the texture to position it as you want
independently of the object you apply it to (just use the
corresponding transform in the texture block). Note that if you use
UV mapping, the texture is naturally at the right position and size
(unless you want the pattern to repeat itself, in which case you will
need to scale it down).
