Getting All Picture URLS in a page

How can i get all picture urls in a page with php. I think we can make it with php but i couldn't do it

 

How about this:

<?PHP

	$page = file_get_contents('a.txt');

	$img_ext[] = 'gif';
	$img_ext[] = 'png';
	$img_ext[] = 'jpg';
	$img_ext[] = 'jpeg';
	$img_ext[] = 'bmp';

	preg_match_all("|src\=([\"'`])(.+?)\\1|i", $page, &$matches);
	foreach ($matches[2] as $val) {
		$file = basename($val);
		$split_file = split('\.', $file);
		if (in_array($split_file[1], $img_ext)) $image_array[] = $val;
	}
	
	echo '<pre>';
	print_r($image_array);
	echo '</pre>';

?>

PHP:
