Thank you very much Chris. You hit the nail right on the head with that one
and it has been annoying me for too long. I did have to play with it a bit
to get it right though. Instead of your version I ended up with this.

pigment{image_map {sys "Test.bmp"} scale 4 rotate x*90 translate <-2,0,-2>}

I found that if you translate before you rotate you end up with two half
images tiled verticaly. Does that sound feasible or am I making it up as I
go along?

Regards David
