Script to sub-divide an image into 4x6s.

I have modified the script and added a checkbox, if ticked it will save and close each new section, save them as jpg with a quality of 12 into a folder off the active documents folder called Chop-O-Matic. If it's a new document that hasn't been saved the folder will be created on the desktop. On completion the new folder will be opened.
