[opendir() issue]

i want to load my files from a directory into an array. my code thus far is
<?php
#set up the array

$dir = "/images/hand/";

$files = array();
$directory = opendir($dir);
while($filename = readdir($directory)){
if(strlen($filename) > 2){
array_push($files, $filename);
}
}

foreach($files as $name)
{
echo "<img src='$name.jpg'> <br>";
}
?>

i get the error:
Warning: opendir(www.sbwelding.com//images/hand/) [function.opendir]: failed to open dir: Invalid argument in C:\serve\www\hand.php on line 12

Warning: readdir(): supplied argument is not a valid Directory resource in C:\serve\www\hand.php on line 13
i have php 5 and have tried using the whole url and it doesnt work. if u have heard of this problem before i would appreciate the help. i am trying to make the script automatically load every pic in my folder.
