How to protect data cd's?

Hi :cool:
I’d like to protect some data cd’s (mostly picture files).
My ideia is to create a thumbnail or a presentation to show some pictures recorded in cd and prevent my friends from copying it. I’ve searched trough the internet but only found audio cd’s protection.
If you have any ideias how to do it or recommend some software, i’d be thankful. :slight_smile:
