"Geht nicht" ist keine sinnvolle Fehlerbeschreibung. Was passiert, wenn du das Skript aufrufst? Gibt es eine Fehlermeldung, wenn ja, wie genau lautet die? Bitte VOLLSTAENDIG reinkopieren, und nicht paraphrasieren.
Und das Skript muss mit dem Bild als Argument aufgerufen werden.
Tschuldige! Mein Fehler, vergessen reinzukopieren.
Also hier wie ich deinen Code ausführe:
