 * Note, When using hoot_get_image_size_name(), any span below 3 gets upgraded to span3, thereby
 * getting bigger images which display much better on smaller screens (where all spans become 100%)
 * Effectively, this means on a grid of 1260, custom images sizes should have atleast 315px width as
 * images below this width would not be used by this function.

 * Note, order of sizes in this array matters. hoot_get_image_size_name() automatically returns the
 * first image size it finds matching the width needed (and matching crop criteria).
