/* Change date: July 18,2003
   Changed by: Michael Sullivan
   Description: 
   	1. Removed unused legacy code
   	2. BuildItem: Added if statements to correctly format the jpg name to correspond to 3 digit format i.e. 001.jpg - 999.jpg
	3. Note that pictureLimit is the first invalid picture number
