 * Version: 1.01a
 * Created: 2001-??-??	First working version
 * Updated: 2002-03-28	Fixed issue when starting with a non png image and
 *                      switching between non png images
 *          2003-01-06	Fixed RegExp to correctly work with IE 5.0x
 *          2004-04-25  Fixed PNG image printing, eliminated need for external
 *                      GIF file, fixed intermittent uninitialised variable
 *                      error [by AG, <http://www.scss.com.au/family/andrew/> ]
 *          2004-09-30  Reverted inline javascript image to transparent GIF. The
 *                      new XP SP2 'security' measures prevented the JS image
 *                      from working. [by AG]
 *          2004-10-22  Rewrote fixImage() to try and work around some reported
 *                      problems with PNGs vanishing! [by AG]
 *          2004-12-12  Fixed problem with PNGs not being restored after
 *                      printing. I have no idea how I missed this one! [by AG]
 *          2005-03-26  Fixed supported RE mis-identifying IE 5.0/Win98 as
 *                      'supported'.
 *          2006-03-12  Fixed problem where images with no width/height
 *                      specified would disappear (realWidth/realHeight) (thanks
 *                      to Julian).
 *          2006-04-05  Escaped realSrc in filter creation.
 *          2006-07-19  Changed escape() to encodeURI()
 *
