displaying all images in a dir

[baconDelta]

so i found a bit of code to display all images in a chosen directory, it goes something like this:

          <?php
    $dir = '/r/';
    $imgs = array();

    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            if (!is_dir($file) && preg_match("/\.(bmp|jpe?g|gif|png)$/", $file)) {
                array_push($imgs, $file);
            }
        }

        closedir($dh);
    } else {
        die('cannot open ' . $dir);
    }

    foreach ($imgs as $idx=>$img) {
        $class = ($idx == count($imgs) - 1 ? ' class="last"' : '');
        echo '<img src="' . $dir . $img . '" alt="' . 
             $img . '"' . $class . ' />' . "\n";
    }
?>

but i keep getting the 'cannot open' message. my images are in mywebsite.com/r/ so i set the dir as /r/ but i can't figure out why it's not able to open the dir. any ideas?

well i figured out an alternative pretty quick, so i guess this thread is pretty useless now lol. since i store the urls in a db i used:

 require_once("../functions/connection.php");
  
    $result = mysql_query("SELECT * FROM store", $connection);
    if(!$result){
        die("query failed");
    }
    while($row = mysql_fetch_array($result)){
        echo "<img src=\"http://www.mywebsite.com/".$row["url"]."\"><br />";
    }
?> 

seems like a better way. perhaps the best way? self resolved thread!
