Hallo!
Will Lightbox verwenden. Habe schon das passende Plug-In, welches auch perfekt funktioniert. Nur funktioniert es nicht mit einem anderen unverzichtbaren javascript meines themes. Nun die Frage, ist es moeglich, den Plug-In zu veraendern, sodass der javascript Code nur eingefuegt wird, wenn man sich nicht auf der index.php befindet.
Hier der Code des Plug-Ins:
PHP
<?php
/*
Plugin Name: Lightbox 2
Plugin URI: http://www.stimuli.ca/lightbox/
Description: Used to overlay images on the current page. Lightbox JS v2.2 by <a href="http://www.huddletogether.com/projects/lightbox2/" title="Lightbox JS v2.2 ">Lokesh Dhakar</a>. Mad props to <a href="http://0xtc.com/" title="visit his site">Tanin</a> for his crucial regular expression code! You rock!!

/* Set the default theme to Black */
add_option('lightbox_2_theme', 'Black');
add_option('lightbox_2_automate', 1);

$options_page = get_option('siteurl') . '/wp-admin/admin.php?page=lightbox-2/options.php';

function lightbox_2_options_page() {

Danke euch im voraus!
P.S. Falls es etwas erleichetert, ich brauche es nur in der single.php, sprich beim lesen der Posts. Anderswo ist es nicht noetig, stoert aber auch nicht, ausser halt der index.php.
