Parameter description:
$max_file_size : upload file size limit, unit BYTE
$destination_folder: Upload file path
$watermark : Whether to add a watermark (1 means adding watermark, others means not adding watermark);
Instructions for use:
1. Remove the ; number in front of the "extension=php_gd2.dll" line in the PHP.INI file, because we need to use the GD library;
2. Change extension_dir = to the directory where your php_gd2.dll is located;
