Code to ENABLE right click file save on 7.1?

I'm using 7.1 and I want to bring back the function to right-click save images on the website. I have found code that disables that function in previous versions of Squarespace, but nothing that will enable it to work on 7.1.

I have zero experience creating custom code, so I would greatly appreciate it if someone could write up or share the code to enable file saving on 7.1 websites! Thank you so much!
