/********************************************************
*    Module: generic rollover scripts
*    Version: 1.1
*    Author: paolo@liquidvision.com
*
*    Description:
*        - preloadImages()
*        - swapImgs(imgName,imgSrc)
*        - changeHTML(id)
*
*    Usage:
*        - Call this JS file from whatever an image rollover function is required.
*        - Populate the IMG_NAMES Array with relevant images.
*        - Call the preloadImages() function ONLY from the homepage. 
*           Eliminates likelihood of incorrect pathing (i.e. broken images).
*        - changeHTML(id) given an id can be used to change the contents 
*        - of an HTML container.
*
*     Change log:
*           - 12-11-2004 - beta version 0.1
*           - 11-01-2005 - version 1.0
*                    - pathing logic removed to make
*                      more generic and reusable.
*           - 28-06-2005 - version 1.1
*                    - changeHTML(id) funciton added for greater rollover option
*                    - preloadImages debugs
