function uploadimage()
    {

        $file_name                  = $this->input->post('fileName');
        $imageName                  = 'set_'.file_name($_FILES["file"]['name'],date('Ymd_his'));
        $config['image_library']    = 'gd2';
        $config['source_image']     = $imageName;
        $config['create_thumb']     = TRUE;
        $config['maintain_ratio']   = TRUE;
        $config['master_dim']       = 'width'; 
        upload_resize('file','settings', $imageName );
        $config['width']            = 200;
        $config['height']           = 62;

        $this->load->library('image_lib', $config);
        $this->image_lib->initialize($config);
        $this->image_lib->resize();
        $this->image_lib->clear();
        $json_data = array(
                'error'     =>false,
                'tmp_name'  =>$file_name,
                'file_name' =>base_url().'assets/uploads/settings/'.$imageName.'?dummy='.rand(0,1000),
                'file_path' =>$imageName
        );

        echo json_encode($json_data);
    }
}

this code upload image to folder before save to table.
