If I understand you correctly, you want to achieve the same effect, but 
without resorting to gimp, and instead you want to let POV-Ray do the 
job, right?

The so-called "repeat warp" is probably what you want.

Yes! Thanks!

    #declare Texture_003 = pigment{
        agate
        agate_turb 2
        color_map {
            [0 color rgbf<0,0,0,1>]
            [1 color rgbf<1,1,1,0>]
        }
        warp {repeat x*2}
        frequency 2
        scale <-1,0.02,1>
    }
    #declare Texture_004 = pigment{
        agate
        agate_turb 2
        color_map {
            [0 color rgbf<0,0,0,1>]
            [1 color rgbf<1,1,1,0>]
        }
        warp {repeat x*2}
        frequency 2
        scale <1,0.02,1>
    }
    #declare Tex_back_wall = pigment{
        checker
        pigment{Texture_003}
        pigment{Texture_004}
        rotate <0,90,0>
        translate <0,0.2,0>
        scale <1,20,0.5>
    }

I solved this problem without uv, but uv-mapping doesn't work with warp repeat

Using the "flip" parameter makes it a lot easier:

      #declare Tex_back_wall = pigment{
          agate
          agate_turb 2
          color_map {
              [0 color rgbf<0,0,0,1>]
              [1 color rgbf<1,1,1,0>]
          }
          warp {repeat x*2 flip x}
          frequency 2
      }

It doesn't? That's strange; it /should/ work.
