	You're right, if you want to have several copies of the image, you
need to use planar mapping, scale your image by 1/number on the y
axis and apply a cylindrical warp with an orientation of x.

	Untested sample code:

#include "colors.inc"
camera {
~        location <-4,4,-4 >
~ look_at  <0,0,0>
}

light_source {
~  <-10, 18, -5>            // light's position (translated below)
~  color White  // light's color
}
cylinder {
~   <0,0,0>,
~   <2,0,0>,
~   2
~   pigment {
~     image_map {jpeg "C:\ProgrammePOV-Ray for Windows v3.6\pic.jpg" }
~     scale <1, 1/7, 1>
~     warp { cylindrical orientation y }
~   }
}
