//  JSviwewsource contains various call functions for the JSviewer script via the JSviewpoint.htm file.
//
//  A call function will place text, images or thumbnail(s) on the page based on an array specification.
//  On some event, for instance "onclick", it will set the cookie named "show" and go to JSviewpoint.htm, 
//  which in turn inserts the proper slideform based on this cookie and activates JSviewer onload.
//
//  This script should be included in the head of all pages interfacing with the JSviewer 1.3 slideshow.
//  Alternatively, the functions below could be part of the styleswitcher script, used on all pages.
