okay, it says that

[code]<?php
$dir = "/images/";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
  if ($dh = opendir($dir)) {
      while (($file = readdir($dh)) !== false) {
          echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
      }
      closedir($dh);
  }
}
?> [/code]

should display any files in the "images" directory, but echos nothing. script is located...

domain
    www
          index.php
          test.php
          script.php
          images/
                image.jpg
                image2.jpg
                image3.jpg

You may also want to look at the glob() function (http://www.php.net/glob) which returns all the file names in directory as an array. Then use array_rand() to select one at random.

[code]<?php
$dir = glob("images/*.jpg");
$rand_file = $dir[array_rand($dir)];
echo $rand_file;
?>[/code]
