Lösche mal das: <script type="text/javascript" src="script/snowstorm.js"></script>
Die Lightbox wird beim BBCode-Editor nicht geladen.

[horsti]

hab ich schon

[StefanT]

1) Ich sehe den Javascript-Code nicht mehr auf der Seite eingebunden.
2) Das Stylesheet ist total kaputt. Da sind überall HTML-Elemente drin. Das passiert, wenn der Browser den Code oben als HTML kopiert.

[horsti]

und was kann ich da machen?

[StefanT]

Ich hatte das Problem noch nicht. Du kannst ja das ganze in einem Textdokument zwischenspeichern.

Hallo,

ich habe mich mal rangesetzt und das ganze etwas optimiert () in einem Plugin umgesetzt!

Lightbox 2

Die Dateien im Archiv müssen einfach in das Hauptverzeichnis von MyBB entpackt und das Plugin danach im AdminCP aktiviert werden.

Es werden keinerlei Templateänderungen vorgenommen, falls das jemand interessiert.

Gebt mir einfach bei Problemen/Fragen/Anregungen ein Feedback.

P.S.: Ich weiß nicht, ob das Plugin greift, wenn ihr die Modifikationen hier aus dem Thread per Hand durchgeführt habt. In diesen die manuellen Änderungen rückgängig machen und ganz dem Plugin die Sache in die Hand geben.

Ich habe folgendes Problem:

Ich habe sämtliche Änerungen wie beschrieben "zu Fuss" durchgeführt und es funktioniert soweit auch alles, aber wenn mehrere Bilder vorhanden sind, sollten ja eigentlich die Grafiken "Previous" und "Next" angezeigt werden. Diese werden nicht angezeigt, obwohl die Funktionen richtig arbeiten.

Woran kann das liegen?

Das ist die lightbox.js

Code:
