You are right. I forgot that the _image struct must be initialized.

Use that:

  CGAL::Image_3 image(_createImage(xdim, ydim, zdim, 1,
                                   vx, vy, vz,
                                   1, WK_FIXED, SGN_UNSIGNED));
  ImageIO_free(image.data());
  image.set_data(&data[0]);

The last three parameters, 1, WK_FIXED, and SGN_UNSIGNED depends on the 
value_type of your vector.
