//  Instructions

//  In the page, set up arrays of pic url's

//  Max length of arrays is 6

//  To use more than 6, use more.jpg and back.jpg pics at beginning and end of arrays

//  Continued arrays must be numbered eg. Array1, Array2, etc.

//  changeThumbs('Pic Array') - use to change thumbnails(name must be in quotes)

//  changePic(index) - used to change main window


//  Directories
picdir = "/pics/";
layoutdir = "/pics/layout/";
