Well, just copy what's inside the code tags and paste it in your notepad, then save the file and name it "sig.php" or whatever. Then upload it to your server in the directory where you put your signatures, and instead of using [ img]
http://soulfathermaps.de/images/mysig.jpg[ /img] use [ img]
http://soulfathermaps.de/images/sig.php[ /img]
That should be enough
Ensure the
directory where your sig is has read access allowed to anybody.
