+/**
+ * Lightbox for Pinry
+ * Descrip: A lightbox plugin for pinry so that I don't have to rely on some of
+ *          the massive code bases of other lightboxes, this one uses data
+ *          fields to acquire the info we need and dynamically loads comments.
+ *          It also has a nice parallax view mode where the top scrolls and the
+ *          background stays stationary.
