Steve,

At one point GD had the brain wave to reverse the orientation of the
pixels array.

Try changing this:
	  img->pixels[j][i] = cmap[vv];

To this:
#ifndef USE_GD_1_2
           img->pixels[i][j] = result;
#else
           img->pixels[j][i] = result;
#endif

Oddly, the other driver code in mapraster.c does not seem to handle both
versions but if the i/j name are to be trusted have just been updated to
work with the new GD.

Best regards,
