This project is a script executed locally. Business personnel will put the finished large image materials on Google Drive, and then a Google Drive app will be installed on the machine where the project is located. The purpose is to synchronize the files and materials on Google Drive to the local folder (how to synchronize the files and materials please search by yourself).
I used the Laravel framework, wrote it in the Conslole command line, and periodically executed the script. You can also put it online, connect to Google Drive’s Webhook (I didn’t try it), and automatically trigger the task based on the notification
The project needs to install a third-party Image processing package, and I used the package Intervention\Image to install Composer
