nutze die in der Version 4.6.4 standartmäßige Bildergalerie.
Jetzt habe ich ein Problem.Das Verzeichnis wird sauber aufgelistet und ich kann Bilder auch vergrößern (Bildvorschau).
Jetzt ist aber das Problem, wenn ich in der Großansicht auf zurück gehe, springt Contenido auf die letzte der beiden Seiten (hier erscheint auch ein weiter Pfeil, wenn ich diesen drücke, bin ich wieder auf der eigentl. Seite 1, auf der auch das Bild ist) und nicht auf die erste Seite, wo ich mein Bild eigentl. geöffnet habe.
Wenn ich auf der 2. Seite ein Bild vergrößere und dann auch zurück gehe, habe ich keine Probleme.
Hier mal der Code, habe nur anstatt vor und zurück Navipfeile eingesetzt
Code: Alles auswählen
