hello and welcome to the 4images forum

here is one of them: [Mod] Random image / Zufallsbild (http://www.4homepages.de/forum/index.php?topic=1020.0)

but your file can't be index.html it should be index.php .. BUT you can use javascript to use it in index.html.. here the direct link how to use it: http://www.4homepages.de/forum/index.php?topic=1020.msg126303#msg126303

Thanks I will check that out,

Thank you for the fast reply ! ! !

EDIT: I am not sure what to put at:  define('ROOT_PATH'  and     define('SCRIPT_URL'   

Could you give an example?

I got it to work, just use this code as your random.php and edit you part to where your image gallery is

Code: [Select]

<?php
define('ROOT_PATH', './');
define('SCRIPT_URL', 'http://gallery.rammstein-europe.com/');
include(ROOT_PATH.'config.php');
include(ROOT_PATH.'includes/db_mysql.php');
include(ROOT_PATH.'includes/constants.php');

$site_db = new Db($db_host, $db_user, $db_password, $db_name);
function is_remote($file_name) {
  return (preg_match('#^https?\\:\\/\\/[a-z0-9\-]+\.([a-z0-9\-]+\.)?[a-z]+#i', $file_name)) ? 1 : 0;
}

$sql = "SELECT COUNT(*) as total_images
        FROM ".IMAGES_TABLE." a, ".CATEGORIES_TABLE." b 
        WHERE a.image_active=1 
        AND a.cat_id = b.cat_id 
        AND b.auth_viewcat=".AUTH_ALL." 
        AND b.auth_viewimage=".AUTH_ALL."
        ";
$row = $site_db->query_firstrow($sql);
$total_images = $row['total_images'];

mt_srand((double)microtime() * 1000000);
$number = ($total_images > 1) ? mt_rand(0, $total_images - 1) : 0;

$sql = "SELECT a.image_id, a.cat_id, a.image_name, a.image_active, a.image_media_file, a.image_comments 
        FROM ".IMAGES_TABLE." a, ".CATEGORIES_TABLE." b 
        WHERE a.image_active=1 
        AND a.cat_id = b.cat_id 
        AND b.auth_viewcat=".AUTH_ALL." 
        AND b.auth_viewimage=".AUTH_ALL." 
        LIMIT $number, 1";
$row = $site_db->query_firstrow($sql);
$image_id = $row['image_id'];
$cat_id = $row['cat_id'];
$image_name = $row['image_name'];
$image_comments = $row['image_comments'];
$full_src = (is_remote($row['image_media_file'])) ? $row['image_media_file'] : SCRIPT_URL.ROOT_PATH.MEDIA_DIR."/".$cat_id."/".$row['image_media_file'];

print("
document.write('<a href=\"".SCRIPT_URL."details.php?image_id=$image_id\"><img src=\"".$full_src."\" border=\"1\" alt=\"$image_name\"></a>');
");
?>

Then edit this and place it where you want your image to be displayed

Code: [Select]

<SCRIPT language='JavaScript'  src='http://gallery.rammstein-europe.com/random.php'></SCRIPT>
Also replace replace MEDIA_DIR with THUMB_DIR if you want the thumbnail to be displayed instead
