teesontap on "Plugin doesn't work. Use WooCommerce product image as its category image."

I found this plugin called 'WooCommerce Category Images Modification' by a guy called ashfame but can't get it to work.

This would be very handy for me as I currently have 600 categories and about to add several hundred more.

It's supposed to "Use WooCommerce product image as its category image" so if you don't have a category image set, it borrows a random image from a product in that category and uses that as the category thumbnail. His download link was some crazy tar.gz file so I just zipped the raw php file and installed it that way.

Here is the php file. It would be awesome if somebody could make sense of it and help me out! I am running Kadence Virtue theme if that helps. Thanks in advance.
