alpharaven on "Posts Attachments"

I am sure some of you out there know the answer to this but I can not find the correct solution. Everything that I try give me the wrong results.

I am trying to show the images that have been inserted into a post and display them in the single.php page. I either get all of the images that are in my wordbress blog or the last two images that were imported. All that works but I only want to show the ones in the particular post.

$args = array(
					'post_parent'    => $post->ID,
					'post_type'      => 'any',
					'post_mime_type' => 'image',
					 'numberposts' => -1,
					'post_status'    =>'any',
				);
				$attachments = get_children($args);
				if ($attachments) {
					foreach ($attachments as $attachment) {
						$img = wp_get_attachment_thumb_url($attachment->ID);
						$link =  chop($img,'-150x150.jpg');
						echo "<ul class='workPic'> <li class='thumbframe'>";
						echo "<div class='thumbnail'>";
						echo "<a href='".$link.".jpg' target='_blank'>";
						echo "<img src='".$img."' alt='read more'/>";
						echo "</a></div></li></ul>";
					}
				}

Please help as I have been struggling with this for days and cant seem to figure out the solution. I think its in the $args array but I am not sure.

Thanks!
