[jQuery] Switch image source during toggle

[jQuery] Switch image source during toggle


I have some divs I am toggling and there is a little + sign image I
want to change to a - sign image when the toggle event occurs, but
can't quite figure it out. Here is the toggle code I have (taken from
a helpful post on here):
$j(document).ready(function() {
$j('#answerbox').hide();
$j('a.faq').click(function() {
var faq_id = $j(this).attr('id');
$j('#faq' + faq_id).slideToggle("fast");
return false;
});
});
The image is not contained within the <a> tag, so I guess I need a
separate function to callback.
