der Thread von top zu den Zufallsbildern (http://forum.phpwcms.org/viewtopic.php?f=16&t=22785) ist schon ein bisserl her, aber gerade habe ich in anderem Kontext eine Lösung als RT Render Script erstellt. Dazu habe das Breitsch'sche RAND_IMG_FROM_FOLDER aufgepeppt und nun gibt es ein RAND_N_IMG_FROM_FOLDER.
Benutztung: in CP oder Template das RT verwenden: {RAND_N_IMG_FROM_FOLDER:<<folder id>>:<<number of images>>:<<lightbox size params>>:<<WxHxCROPxQUALITY ALT-Text>>}
Dabei ist
- <<folder id>> = ID des Dateiordners aus der Dateizentrale.
- <<number of images>> = Anzahl der ausgewählten Zufallsbilder (Falls weniger Bilder im Ordner sind, werden weniger Bilder ausgegeben)
- <<lightbox size params>> = WxHxCROPxQUALITY für die Lightbox. Falls leer, wird keine Lightbox erzeugt
- <<WxHxCROPxQUALITY ALT-Text>> = Größe und Alt-Text der Bilder
Bedingung 1: /config/phpwcms/conf.inc.php

folder ID = the ID number of the Folder in the phpwcms file browser - required
number of images = the number of images to create. Will create max. the number of files in specified folder
lightbox size params = Dimensions, cropping and render quality for lightbox image style is WxHxCROPxQUALITY
lightbox popup relies on lightbox script and css include somewhere on your webpage.
<!-- CSS: template/lib/slimbox/slimbox.css -->
<!-- JS: template/lib/slimbox/slimbox.mootools-1.3.js -->
leave lightbox size params empty for no lightbox
WxHxCROPxQUALITY ALT-Text = Dimensions and alt text of the image (alt text only when not used as background image)
if empty and css background image it takes the original dimensions of the image
if empty and not css background image it takes the preview dimensions for the images
