Flash Gallery Galerie für die Webseite

Verfasst von admin am So, 2008-05-25 00:02.

SimpleViewer ist ein kostenloser Flash-Image-Viewer. Die Einstellungen zum Wiedergeben von Fotos werden in einer XML Datei gespeichert. Damit es richtig funktioniert, benötiggt der Viewer nicht nur einen Ordner mit Bildern, sondern auch einen mit Thumbs / Vorschaubildern. Um die zwei Sachen, XML Datei und Thumbs,  zu sparen, habe ich einen Script geschrieben, der sie ersetzt.

Code:
