Codeigniter: Uploaded images permission is 600 in web server, images not displaying in website

我使用codeigniter上传了我的图像，上传的图像没有显示在我的网站上，然后我去filezilla搜索那个文件，文件夹权限是755，但文件权限是600，如果我把文件权限改为644，那么图像显示很好，但我不能这样做所有上传的图像。那么，有什么办法可以补救吗?

            $config['upload_path'] = './assets/images/';
            $config['allowed_types'] = 'gif|jpg|png';
            $config['max_size'] = '100';
            $config['max_width']  = '600';
            $config['max_height']  = '600';
            $config['file_name']  = $id;
            $this->load->library('upload'); 
            $this->upload->initialize($config);
            if(!$this->upload->do_upload())
            {
                $error = array('error' => $this->upload->display_errors());                 
                redirect('', $error);
            }
            else
            {
                chmod($config['upload_path'], 0755);
                redirect('');
            }

此尝试代码更改权限Folder Not File

$config['upload_path'] = chmod('./assets/images/', 0755);
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '100';
        $config['max_width']  = '600';
        $config['max_height']  = '600';
        $config['file_name']  = $id;
        $this->load->library('upload'); 
        $this->upload->initialize($config);
        if(!$this->upload->do_upload())
        {
            $error = array('error' => $this->upload->display_errors());                 
            redirect('', $error);
        }
        else
        {
            $config['upload_path'];
            redirect('');
        }

    $config['upload_path'] = './assets/images/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '100';
    $config['max_width']  = '600';
    $config['max_height']  = '600';
    $config['file_name']  = $id;
    $uploadata = array('upload_data' => $this->upload->data());
    $perfile = $uploadata ['upload_data']['full_path'];
    chmod($perfile ,0777)
