uploading images to FTP

[kaen]

I have a problem. This is my code:

<?
//Get FTP Pass, User, Server, and Category
 $ftp = "SELECT ftp_server, ftp_user, ftp_pass, ftp_cat, address FROM 

layout_servers where 	 ftp_cat = '$_SESSION[cat_id]'"; 
 $ftp_res = mysql_query($ftp) or die (mysql_error());

   while ($row5 = mysql_fetch_assoc($ftp_res)) 
	{ 
        $ftp_server = $row5['ftp_server']; 
        $address = $row5['address']; 
        $ftp_user = $row5['ftp_user']; 
        $ftp_pass = $row5['ftp_pass']; 
        $ftp_cat = $row5['ftp_cat']; 
	}

$conn_id = ftp_connect($ftp_server); 

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user, $ftp_pass); 


// check connection
if ((!$conn_id) || (!$login_result)) { 
        echo "FTP connection has failed!<br>";
        echo "Attempted to connect to $ftp_server for user $ftp_user"; 
        exit(); 
    } else {

ftp_chdir ($conn_id, $_GET[type]);
ftp_mkdir ($conn_id, $_GET[dirname]);

$dir = "temp/$_GET[dirname]/";
$files = array();
$open = opendir($dir);
while ($file = readdir($open)) { if ($file != "." && $file != "..") { $files[] = 

$file; } }
closedir($open);
sort($files);
reset($files);



for ( $i=0; $i < count($files); $i++ ) { 

//Upload
$source_file="temp/$_GET[dirname]/$files[$i]";
$destination_file="$_GET[dirname]/$files[$i]";

$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); 

unlink($source_file);
}

if($upload) {

rmdir("temp/$_GET[dirname]");

echo "Files moved to $ftp_server";
echo "<img src=$address/$_GET[dirname]/$zip>";

} else {
echo "Error uploading. Contact the webmistress immediately.";
}	


}

// close the FTP stream
ftp_close($conn_id); 


//++++++++++++++++++++++++++++++++++++++
}
?>

However, once I upload the two images in the array- when I try to display them with this PHP script:

<?
$thumb = "$server/$cat/$item_id/$item_image";
?>

It says that it's broken. And if I go to the file address itself, it says that the image cannot be accessed. However, if I refresh, it works and works for the rest of the time.

Can you help me?
