[quote author="CroNiX" date="1348600836"]I usually use
FCPATH . 'public/image/'

assuming the "public" dir is at the same level as your index.php

It produces a full path and not a relative one.[/quote]

Hey, I know what is the problem.
This path need to add file_name.

Code:

$data['image']=$file['file_name'];
$output = "./public/image/".$data['image'],

I try like this and work.
thanks for the answer.
