Simple solution: rotate the image to lay across the HF. A common mistake,
not orienting the two. HF lies along a xz plane, like a ground, while images
stand (as seen from default camera) as though projected onto a wall in the
xy plane.

So... rotate 90*x (or <90,0,0>) for the image.

My personal choice of the way to do things like this is to 'translate -0.5',
which centers them, then rotate the image, finally scaling them. That way
they both respond in the same manner.
