Well, I don't have code but there's a number of ways to do it . . .

1. What is code detect links and redirect new link

You could pipe it through a script and read the headers, if you get a 404, redirect.

2 . What is code detect image no longer available and display a new image

If the file is on your server, easy:

if (!is_file($_SERVER['DOCUMENT_ROOT'] . "/$img")) {
$img = $default_img;
}

If it's a remote image, I'd use the same method as in #1.
