simple-image.php error

[fife]

ok so ive found what looks to be a decent image uploader. which if anyone is interested can be found here;

 

http://www.white-hat-web-design.co.uk/blog/resizing-images-with-php/

 

I have followed the instruction and added the few bits needed to make it work properly.  However hence me beening here, it doesnt work.  Im not overly familiar with the syntax of -> so maybe I am outputting the wrong name in the move_upload_file but the error I get on the server is

 

 

Unable to move '/tmp/phpJnOkXP' to bla bla bla upload-new.php on line 126

Upload fail

 

 

which is the move_upload line Here is my code

 

  <?php
	if( isset($_POST['uploadbtn']) ) {
$folder = "{$_SERVER['DOCUMENT_ROOT']}/images/test/";
$fileName = $_FILES['newImage']['name'];
$tmpName = $_FILES['image']['tmp_name'];

      include('../simple-image.php');
      $image = new SimpleImage();
      $image->load($tmpName);
      $image->resizeToWidth(600);
      $image->output();

   
   
  $uploaded =  move_uploaded_file($tmpName , $folder.$fileName);
    
   if($uploaded){
echo "Upload success";   
   }
   else {
   echo "Upload fail";
   } }

	?>
     <form action="" method="post" enctype="multipart/form-data" name="uploadfrm">
     	<input name="image" type="file" />
        <input name="uploadbtn" value="Upload" type="submit" />
