Hey, I just tried it, there is errors in that code.
The code below works for sure:

Put this in the header... change picture1.gif / picture2.gif to the full path to your images, probably something like "images/misc/logo1.gif" and "images/misc/logo2.gif"

<script language="Javascript">
if (document.images) {
    pic1 = new Image;
    pic2 = new Image; 
    pic1.src = 'picture1.gif';
    pic2.src = 'picture2.gif';
    }
</script>

and then for the logo put in the following:

<a href="http://www.juot.net" onMouseOver="document.rollover.src=pic2.src" 
  onMouseOut="document.rollover.src=pic1.src"> 
<img src="picture1.gif" border="0" name="rollover"></a>

Change www.juot.net to your domain and change picture1.gif again to the full path to your logo.

I *think* you have to go to templates -> All Style Options and in the Header box under 'Common templates" make the following change...

find

<a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></a>

and replace it with the logo code from above, which I changed to your forum details:

<a href="$vboptions[forumhome].php$session[sessionurl_q]" onMouseOver="document.rollover.src=pic2.src"  onMouseOut="document.rollover.src=pic1.src" ><img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" name="rollover" /></a>

That should do it... note you want to keep the correct #1 image as your defined logo using the above code, otherwise you can ignore your defined logo and use the following alternate code:

<a href="$vboptions[forumhome].php$session[sessionurl_q]" onMouseOver="document.rollover.src=pic2.src"  onMouseOut="document.rollover.src=pic1.src" ><img src="images/misc/logo1.gif" border="0" alt="$vboptions[bbtitle]" name="rollover" /></a>

minding you will need to change "images/misc/logo1.gif" to the path to your main (un-clicked) logo image.
