Alle Images liegen in fileadmin/gallery/ext_img.
Ich kann habe beim Content Element Bild, Klick-Vergrössern, Lightbox und ausgewählt.
Doch das Einzige was passiert, ist das Klick-Vergrössern.
Und im Browser ein JS_Error bei lighbox-packed.js:
Object.extend is not a function

hat sich erledigt, ich bin gewechselt zu kj_imagelightbox2, und da klappt das auf Anhieb
