Also ich weiß nicht, ob das Sinn macht.tantalus hat geschrieben:Tolles Modul,
jetzt habe ich nur noch ein Problem: hat jemand eine Idee wie man auf jeder erzeugten Vorschauseite einen individuellen Text eingeben kann?
Auf welcher Seite welche Bilder sind kann man nämlich nicht festlegen.
Die Reihenfolge der Bilder entspricht der Reihenfolge im Dateisystem.
das scheint mir dann fast eher eine aufgabe für eine artikelliste zu sein...
