在Php中，两个图像不能同时创建缩略图

我正试图上传两个图像（“图像”和“封面图像”）同时与缩略图，但第二个代码/“图像” 未创建缩略图且未上载到文件夹，第一个代码/“coverimage”工作正常，但“image”未创建缩略图 我错在哪里？这是我的密码

//uploading image ( working fine and creating thumbnail)
if( isset( $_FILES['CoverImage'] ) ){
            if (file_exists($_FILES['CoverImage']['tmp_name']) || is_uploaded_file($_FILES['CoverImage']['tmp_name'])) 
                {
                    $filenames = time() . uniqid(rand()) . $_FILES['CoverImage']['name'];
                    move_uploaded_file($_FILES["CoverImage"]["tmp_name"], "ShopCoverImage/" . $filenames);
                    $source_paths = $_SERVER['DOCUMENT_ROOT'] . '/ShopCoverImage/' . $filenames;
                    $target_paths = $_SERVER['DOCUMENT_ROOT'] . '/ShopCoverImage/thumb/';

                    $this->image_lib->clear();
            }

                    }
                    $this->image_lib->clear();
            } 
        }

请使用以下代码：

从第二个上载图像代码中删除

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

并替换为以下代码

$this->image_lib->initialize($config_manip);

替换代码“无法加载请求的类：图像库”后显示以下错误
