Because it is. Use UV maping to make it follow the surface of the object.

You can scale the image to your object: image_map {jpeg
"07-2312-482.jpg" map_type 0 scale<5,5,1>}

Think of any texture as an infinite solid out of whitch you carve out
whatever object you apply it to. In the case of an image_map, each image
pixel stretch out infinitely along the z axis.
