/*===================================================================
** LinkDev Usage (Ahmed Waly):
-----------------
Used in EHTN Project for the follwoing components:
- Photo Library (Printouts)
Note: Used in compatibility with Mootools version v1.2.1
These files used in the component:
- slideshow.js
- mootools121.js
- lightbox.js
** Also i modified it to split the sent title (if sent) by :: and 
show its [0] index Caption area, [1] index as date, and the [2] index in description area.
