Like in a 3D array, by xy-slices. See the following function in 
<CGAL/ImageIO.h>:

template <typename Word>
inline
Word
static_evaluate(const _image* image,
                const unsigned int i,
                const unsigned int j,
                const unsigned int k)
{
  return ((Word*)image->data)[(k * image->ydim + j) * image->xdim + i];
}

The first words in the image are those for k==0, y==0, and x varying. Then xy-
varying.

I do not know if that answer your question. I am not a specialist in 3D 
images 
representations.
