To make fading images in your document you need to put the the following in the HEAD section of your document :-

<!-- *** BEGIN CUT - Start Code *** -->
<!-- (* Another free JavaScript from JavaScript-FX.com *) -->
<SCRIPT LANGUAGE="javascript" SRC="javascript/JSFX_ImageFader.js"></SCRIPT>
<!-- *** END CUT - End Code *** -->

Put the following on the BODY of your document, where you want the link :-

<A HREF="home.html"><IMG
    SRC="images/home.gif" BORDER="0" NAME="home"
    onMouseOver="JSFX.fadeUp(this)"
     onMouseOut="JSFX.fadeDown(this)"
     class="imageFader"
></A>

If you want to change the speed of the fadeUp fadeDown put the following in the BODY of your document, where you want the link :-

<A HREF="home.html"><IMG
    SRC="images/home.gif" BORDER="0" NAME="home"
    onMouseOver="JSFX.fadeUp(this, 20)"
     onMouseOut="JSFX.fadeDown(this, 5)"
     class="imageFader"
></A>

Where
20 is the fade up step
5 is the fade down step
The higher the number, the faster the fade. Multiples of 100 work best.
1, 2, 4, 5, 10, 20, 25, 50.
