The .show/hide-for-[size] and .show/hide-for-[size]-down classes are

Orbit fix / Run images_loaded callback if images.length == 0

This caused the orbit slider to not load/init. If orbit is used as content slider and not as images slider than the callback image_loaded in L287 (foundation.orbit.js) is never fired.

So the callback needs also to be fired if the image array is empty.
