// RollOver.js runs through all images loaded into a page,
// and build arrays for gif and jpg images.
//--------------------------------------------------------------------
// Useage:
// load(imagePath,on,off,showLoad) - specify path to rollover
// directory, extension for 'on' and 'off' conditions of the roll over.
// Place load in the body tag inside 'onload=""' statement.
// 'showLoad' can be set to either 'true' or 'false' to toggle the
// presentation of images set for roll over.
//
// on(imageName,type) - specify image name (same as 'name=""' tag in
// image), and the type (either 'gif' or 'jpg'). place in
// 'onmouseover=""' attribute of either anchor or image map tag.
//
// example: onmouseover="if(on)on('imageName','gif')"
//          onmouseout="if(off)off('imageName','gif')"
//
// Note:    imageName should EXCLUDE suffix use for on and off in the
//          load() call of your body tag.
//
// off(imageName,type) - same as on() - EXCLUDE suffix
