JQuery :: Getting Child Attribute - Images With URL / Descriptions

With this code:
<div id="main"><div id="slideshow" class="pics">
<a href="/page2.asp""><img src="/img01.jpg" alt="Text 1" /></a>
<a href="/page3.asp"><img src="/img02.jpg" alt="Text 2" /></a>
</div><p id="pcaption"></p></div>

I'm trying this to no avail (using the Cycle plugin, the source html DOES have the includes for jQuery and cycle external files):
$(function() {
$('#slideshow').cycle({
fx:'fade',
fit: 1,
pause: 1,
timeout: 1000,
height: 360,
width: 550,
random: 1,
after: function() {
$('#pcaption').html(["this.children"][0].attributes[0].childNodes[0].data);
}});});

The problem line is:
$('#pcaption').html(["this.children"][0].attributes[0].childNodes[0].data);
What I am trying is to get the text from the alt attribute to change the <P> after the image.

I've tried:
$('#pcaption').html(this.alt);
$('#pcaption').html(this.children.alt);
And I still can't get the alt text from the image tag. I want to have images with an URL, but I need them to have descriptions (that's why the ALT in each image).
