        parent::__construct();

        $this->load->helper('form');

        $this->load->helper('url');

    }  

    function index()

    {

        $this->load->view('upload_view');

    }

    //Upload Image function

    function uploadImage()

    {

       $config['upload_path']   =   "uploads/";

       $config['allowed_types'] =   "gif|jpg|jpeg|png"; 

       $config['max_size']      =   "5000";

       $config['max_width']     =   "1907";

       $config['max_height']    =   "1280";

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

       if(!$this->upload->do_upload())

       {

           echo $this->upload->display_errors();

       }

       else

       {

           $finfo=$this->upload->data();

           $this->_createThumbnail($finfo['file_name']);

           $data['uploadInfo'] = $finfo;

           $data['thumbnail_name'] = $finfo['raw_name']. '_thumb' .$finfo['file_ext']; 

           $this->load->view('upload_success',$data);

           // You can view content of the $finfo with the code block below

           /*echo '<pre>';

           print_r($finfo);

           echo '</pre>';*/

       }

    }

    //Create Thumbnail function

    function _createThumbnail($filename)

    {

        $config['image_library']    = "gd2";      

        $config['source_image']     = "uploads/" .$filename;      

        $config['create_thumb']     = TRUE;

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

        if(!$this->image_lib->resize())
