 <img href="<?=$gambar?>">

Controller

 public function render()
	{
		$method = $_SERVER['REQUEST_METHOD'];

		if($method != 'GET'){
			$jsonAr = array(
				"_meta" => array('status' => 'ERROR','count' => 1),
				"result" => array('errorCode' => 400,'userMessage' => 'Bad request')
			);
			json_output(400,$jsonAr);
		} else {
			$this->load->model('m_gambar_produk');
			$name = $this->input->get('filename');
		    $response = $this->m_gambar_produk->render($name);
			if ($response['errorCode']  == 200) {
				$stat = "SUCCESS";
			} else {
				$stat = "ERROR";
			}
			$count = array($response);
			if ($response['errorCode']  == 200) {
				$result = array($response);
			} else {
				$result = $response;
			}
			$jsonAr = array(
				"_meta" => array('status' => $stat,'count' => count($count)),
				"result" => $result
			);
			json_output($response['errorCode'],$jsonAr);
		}
	}

Model

public function render($name)
    {
        $q  = $this->db->select('filename')->from('gambar_produk')->where('filename',$name)->get()->row();

        $file = $q->filename;
        $gambar= base_url('gambar_produk/'.$file);
        if($q == ""){
            return array('errorCode' => 401,'userMessage' => 'Filename Not found');
        } else {
            return array('errorCode' => 200,'userMessage' => $gambar);
        }
    }

pertanyaanya ketika saya mau akses variabel $gambar atau http://localhost/rest_server/gambar_produk/render?filename=e5ce7e-f4a36d-ccbe71-47d3e2-ad4664-d3.jpg muncul gambar sesuai filename yang di input bagaimana ya?????
