Random carousel für Foldergallery

Schön Abend !

Damit nicht immer jahreland die gleichen Bilder im Carousel kreisen, hab ich das droplet Random-image bißchen aufgebohrt.
Es übergibt nun einen carousel div mit derzeit 7 zufällige Bildern aus einer Baumstruktur z.B der Foldergallery
für die colorbox vorbereitet.

eine zeit lang wohl im Testgebiet:

Code:

//: [[Random_carousel_fg?dir=<Verzeichnis>&height=<Pixel>&width=<Pixel>]]
//: leave width free!
//: It is like Random image - it uses foldergalley recursive and is prepared for colorbox.
//: $name is not used, jet.

global $suffixes, $thumbs, $thumbdir, $f_time, $f_latest;

// config
$thumbdir = 'fg-thumbs'; // sub directory for thumbnail images
$suffixes = 'jpg|jpeg|gif|png'; // recognized file suffixes for images
$random = 1;
// end config

$thumbs = isset( $thumb ) ? 1 : 0;
$random = isset( $latest ) ? 0 : 1;
$folder = WB_PATH.MEDIA_DIRECTORY.'/'.$dir;
$names = array();
$dir_handle = @opendir($folder);
$names = recurse_dir( $dir_handle, $folder );

if ( $random ) {
shuffle($names);
$image=$names[0];
$image2=$names[1];
$image3=$names[2];
$image4=$names[3];
$image5=$names[4];
$image6=$names[5];
$image7=$names[6];
}
else {
$image = $f_latest;
}

$name = $image;
if ( preg_match( "#/(\w+)\.\w+$#", $image, $match ) )
{
$name = $match[1];
}

$name = "Zufallsbilder" ;
