thanks guys solve problem. via loading library in constructor

 $this->load->library('image_lib'); 

after added 2 line code

 $this->image_lib->clear();  $this->image_lib->initialize($img_array); 

and remove line

 $this->load->library('image_lib', $img_array); 

my final code

public function add_images(){      $this->form_validation->set_rules('description','description','required');     $this->form_validation->set_rules('status','status','required');      if($this->form_validation->run() == true) {          // print_r($this->input->post());         $config['upload_path'] = 'public/img/inner_images/';         $config['allowed_types'] = 'gif|jpg|jpeg|png';   // upload valid images                     // update library setting of upload         $this->load->library('upload', $config);         //upload image          $this->upload->do_upload('image');         $finfo = $this->upload->data(); // info of uploaded file          //for image resize         $img_array = array();         $img_array['image_library'] = 'gd2';         $img_array['maintain_ratio'] = true;         $img_array['create_thumb'] = true;         //you need setting tell image lib image process         $img_array['source_image'] = $finfo['full_path'];         $img_array['width'] = 113;         $img_array['height'] = 75;          $this->image_lib->clear(); // added line         $this->image_lib->initialize($img_array); // added line         if (!$this->image_lib->resize())         {             echo $this->image_lib->display_errors(); exit;         }         if($finfo['file_ext'] ==='.gif'||$finfo['file_ext'] ==='.jpg'|| $finfo['file_ext'] ==='.jpeg' || $finfo['file_ext'] ==='.png'|| $finfo['file_ext'] ===''){             $insert = array(                 'inner_image' =>$finfo['file_name'],                 'description' => $this->input->post('description'),                 'status' => $this->input->post('status')             );             $check = $this->mdl_inner->add_image($insert);             if($check){                 $this->session->set_flashdata('success',"image added sucessfully");                 redirect('admin/inner_gallery/add_images/', 'refresh');               }         }else{             $this->session->set_flashdata('error',"upload proper image format");             redirect('admin/inner_gallery/add_images/', 'refresh');         }     }     $arrdata['middle'] = 'admin/inner/add_image';     $this->load->view('admin/template',$arrdata); }
