Answer 1

What do you see on the console when you you add this
echo "<pre>";
print_r($result);
echo "</pre>";exit(0);
after $result=htmlspecialchars(json_encode($result), ENT_NOQUOTES);

Answer 2

Make sure your upload folder exists. Yii::app()->baseUrl returns '...yourproject/protected'.
I use:$folder=Yii::app() -> getBasePath() . "/../images/";
Also check your console in browser(press F12). If you got 403 error, then add rules to your controller for upload action
public function accessRules()
{
return array(
array('allow', // allow all users to perform 'index' and 'view' actions
'actions'=>array('index','view','upload'),
'users'=>array('*'),
),
.....
