* File    : JSFX_ImageFadeSwap.js  © JavaScript-FX.com
* Created : 2001/08/31 
* Author  : Roy Whittle  (Roy@Whittle.com) www.Roy.Whittle.com 
* Purpose : To create a more dynamic image swap using opacity
* History 
* Date         Version        Description 
* 2001-08-09	1.0		First version
* 2001-08-31	1.1		Got it working with NS6 - You must use opaque
*					GIF's and use a STYLE attrib in the main
*					HTML Page - Thanks Owl.
* 2001-08-31	1.2		Added different FadIn/FadeOut and converted
*					all vars to JSFX name space.
* 2001-09-01	1.3		Make it so you only need one onMouseOver
*					onMouseOut in the main document.
* 2001-09-09	1.4		Allow you to do a "Swap Other Image" so
*					you can swap the same image with different pictures.
* 2001-09-17	1.5		Create the pre-loading object - just like
*					simple rollovers and animated rollovers.
*					allows for a similar interface to all.
* 2001-09-18	1.6		The code contains so much of SimpleRollovers that
*					I added imgOn and imgOff so you can mix rollovers
*					without having to include 2 ".js" files.
* 2002-02-08	1.7		If the ON image is already loaded don't reload it.
*					This should help with the IE bug that reloads images
*					from the server even though they are pre-cached.
*					(will not work for swapping multiple pictures into same Image object)
* 2002-02-13	1.8		Corrected a bug in JSFX.findImg
* 2002-04-23	1.9		Write out the style tag.
* 2002-06-09	1.10		Attempt fix for IE on a Mac
* 2002-08-27	1.11		Fix a bug whereby opacity may go over 100 which
*					may be causing a bug in IE6
* 2002-08-29	1.12		Thanks to piglet (http://homepage.ntlworld.com/thepiglet/)
*					I now have a partial fix for NS7 and Mozilla 1.1.
