Html->image('uploads/'.$val1[0]['Upload']['filename']);
//echo 'Html->url(array('controller' => 'uploads','action' => 'download',$val1[0]['Upload']['filename'])).'" width="100" height="100"/>';
?>

if (move_uploaded_file($tmp_name['tmp_name'],WWW_ROOT."/img/uploads/".$file['name']‌​)) { /* conditions*/ }
$data=$this->Upload->find('first',array('conditions'=>array('filename'=>$filenam‌​e)));
echo $this->Html->image('uploads/'.$val1['Upload']['filename'],array('class'=>'media-‌​‌​object img img-thumbnail','alt'=>$val1['Upload']['filename']) );
