Modify JavaScript to use ASCII character or image instead of text
<p>I have a DIV that expands or collapses when clicked.  There is a + sign to indicates it expands, which changes to a - sign to indicate you can collapse it. Instead of the + and - sign, I want to use up and down arrows.</p>

<p>jsfiddle here: <a href="http://jsfiddle.net/9PzRr/" rel="nofollow">http://jsfiddle.net/9PzRr/</a></p>

<p>I changed the .text to .html and plugged in the unicode values for the up/down arrows in place of the + and - symbols, but only the down arrow would show.  I'm open to using an image instead of the ASCII characters, but I am not familiar enough with Javascript/jQuery to know how to tell it to display an image instead of text.</p>

<p>Thanks for any help.</p>
