$config['upload_path']          = './berkas/content/';
$config['allowed_types']        = 'gif|jpg|png';
$config['max_size']             = 0;
$config['max_width']            = 1024000;
$config['max_height']           = 7680000;
$config['encrypt_name']           = TRUE;
$config['overwrite']           = FALSE;

$this->load->library('upload', $config);

        $upload_data = $this->upload->data();
        $file_name = $upload_data['file_name'];            
        $params['gambar'] = $file_name;
        $this->load->library('image_lib');
        $config['image_library'] = 'gd2';
        $config['source_image'] = './berkas/content/'.$file_name;
        $config['create_thumb'] = FALSE;
        $config['maintain_ratio'] = TRUE;
        $config['width']     = 550;
        $config['height']   = 350;

$params = array('gambar' => $file_name);
