How do I auto resize image once pasted to ms word 2021?

Hi, I have around a hundred photo files that I want to paste onto a single Word document. However, the photos are in different sizes and will be printed on paper at various sizes in the future.

I would like the pasted images to automatically stretch to fill the entire Word page. This way, when I change the paper size, margins, etc., they will adjust and fill the Word page appropriately.

Is there any way to achieve this?
