Function "largeImages" Replaces content -mobi images with ones for desktop
1. Place the two images in the same folder 
2. Name the mobile version "imagename-mobi" using matching "imagename" for the desktop version 
3. Assign ID attribute to the image container 
Notes: Both images should have matching type file extention. Some image file types may not be suitable for all mobile devices. The Script assumes the existence of a desktop version image.

Function "popupLinks" adds Target attribute to links with Rel attribute value "blank"
The reason: Currently many mobile devices do not support more than one window and DOM Scripting
