jon11x on "get image url, how to?"

Hello,

i have something like that...

var __aa_page_url = '<?php the_permalink(); ?>';
var __aa_page_image_url = 'http://test.com/images/sample-image.jpg';
var __aa_page_title = '<?php the_title(); ?>';
var __aa_page_description = '<?php echo $post->post_excerpt; ?>';

Everything works great, except image post url. What code should i put there, so it extracts image url from my post?
