I tried to select all the pictures, which is rather tedious, and upload them

1. to Google Drive, but if >100 pictures, Google Drive won't upload all the images.
2. to SendAnywhere, but this would take over an hour. However, I [cannot](https://apple.stackexchange.com/q/415979/20338) disable auto-lock on my iPad (iPadOS 13) (the maximum auto-lock period is 15 minutes), and whenever the iPad gets locked, uploads are stopped.

How can I move my photos from my iPad storage to my Windows 7 computer without a USB cable, AirDrop and iCloud?
