<script type="text/javascript">
  Dropzone.options.imageUpload = {
    maxFilesize:1,
    acceptedFiles: ".jpeg,.jpg,.png,.gif"

$uploadDir = 'uploads';

if (!empty($_FILES)) {
 	$tmpFile = $_FILES['file']['tmp_name'];
 	$filename = $uploadDir.'/'.time().'-'. $_FILES['file']['name'];
 	move_uploaded_file($tmpFile,$filename);
}

?>
