                {
                        $ext = substr(strtolower(strrchr($image['name'], '.')), 1); //get the extension

                        if(in_array($image['type'], $imageTypes))
                        {

                                $rand = rand(100000,999999);
                                $link = 'pic_' . date_format($date, 'U') . '_' . $rand . '.' . $ext;

                                move_uploaded_file($image['tmp_name'], $uploadPath . $link);

                                $this->Picture->create();
                                $this->Picture->set(array('name' => $image['name'], 'link' => $link));
