How to make it works?

I set this configuration for an ecommerce website with thousands of pictures too, but I don’t see any changes after saving the configuration , here the screenshot: https://screenrec.com/share/5Gs8d9pwiO

I just would like to set ALT and TITLE like the produt title , is it possible?
