// -------------------- Image Scroll ---------------------------------------------------- 
// Image Scroll version 1.3
// By Robin Mayne
// Copyright 2001 BioWare Corp. All Rights Reserved.
// 1.0 - 2001: RM created
// 1.3 - Jan 7 2003: RM - updated to work with screenshot galleries

//----------------------------------
// How to use:
// 1) load this Image Scroll script into the page
// 2) locally on the page, populate imgName[] with an array of the image names that will change
// 3) locally on the page, set arraytype to appropriate type
// 4) locally on the page, populate scrollobj[] by calling scrollInfo() or scrollGall()
// 5) scrollOver(), scrollGoTo(), and scrollLinkStatus() can now be called from the page to create
//    scrolling imagery that links to either URLs or pop-up windows
// NOTE: this script currently calls openScreenWin() from section_gallery.js, and can be used with
//       fncImageScrollJS() in gallery.inc.php to use php to do step 4 above.
//----------------------------------

// Set the document images names that will be replaced, in the order they appear on the page
// var imgName = new Array("footerlogo1","footerlogo2","footerlogo3","footerlogo4");
// 1.3 - imgName now set where scrollobj[] is populated
var imgName;
// Set the info for each item in the scroll set, by loading into an array
var arraynum = 0;
// flag for array type. 1 = rollover images, 2 = gallery images

//   (starts at 1, but can be set locally when these scripts are called
//   to correspond to actual position of starting images - eg. randomized starting position)
