[WP Smush Pro] Bulk Restore Original Images Script

Hello,

Smush Pro is not working well with the images on our website and it's making them to pixelated, therefore, we would like to restore the original unoptimized images on the website.

We would like to ask for the bulk restore script as what we have read in the article below:

We have enabled the "Store a copy of my full size images" option.

Looking forward to your response.
