Script not working

[Anirban1987]

This script works well in local wamp server when it is called from flashplayer10 through a FileReference object . Actually when an upload button is clicked the script is called through fr.upload() .... but it does not work in server . though upload progress is seen , no error is thrown . Please help.

 

<?php
session_start();
include('SimpleImage.php');
if(isset($_FILES['Filedata']['name'])){
   $myimage = new SimpleImage();
   $myimage->load($_FILES['Filedata']['tmp_name']);
   $h=$myimage->getHeight();
   $w=$myimage->getWidth();
   if($h>=$w){$myimage->resizeToHeight(50); }
   else{$myimage->resizeToWidth(50); }
   $myimage->save('alluploads/'.basename($_FILES['Filedata']['name']));

}
?>
