Accordion menu switch image + to - on click
<p>I have a jQuery accordion menu on my site. I didn't write the code (only 2 semesters of C++), I got it <a href="http://www.ashishblog.com/blog/left-menu-accordion-using-jquery-in-aspdotnetstorefront/" rel="nofollow">here</a>. If I knew more about this stuff, I probably could have worked one of the solutions to similar questions on here into the code, but I don't know how. I'd like to just make the image switch from + to - when it's clicked on so people know it opens to a menu and what not. Here's the code:</p>

<pre><code>&lt;script type="text/javascript" &gt;
$("#accordion &gt; li &gt; div").click(function () {
    if (false == $(this).next().is(':visible')) {
        $('#accordion ul').slideUp(300);
    }
    $(this).next().slideToggle(300);
});
&lt;/script&gt;
</code></pre>

<p>Any help is very much appreciated... Thank you!</p>
