1. Leere Ordnerauswahl im Eingabemodul
2. Fehler im Ausgabemodul mit getimagesize
Habe lange im Forum gesucht und an verschiedenen Stellen die Lösung zusammengesucht. Eingabe und Ausgabemodul stammen aus verschiedenen Beiträgen.
Das ganze ist also nicht auf meinem Mist gewachsen. Danke für die Hilfe!
Ich habe das ganze mal hier zusammengebracht. Bei mir läuft die Galerie jetzt einwandfrei
1. Leere Ordnerauswahl im Eingabemodul
Lösung:
Die Funktion array_merge wurde in der PHP Version 5 überarbeitet.
Den Hinweis fand ich hier:
