Online batch thumbnail generation tool (PHP)

illustrate:
----------------
This program batches the pictures in a folder that meet the requirements into thumbnails of a specified size.
and place it in a new folder.
Thumbnails are lossless.
Soon, we will release a direct-read catalog photo album based on this program.

Set index.php:
----------------
//Only process files with some tags in their file names. If you want to process all files, please set to .
$only = . ;
//If you do not want to overwrite the existing image, set this line to 0;
$over = 1;
//Whether to process GIF images, 0 means no processing
$regif = 1;
