How can I make it so when I like or comment on a photo on facebook none of my friends can see I that I did?

Like when you like someones status or picture and you comment on the photo all of your friends can see that you commented or liked this persons picture even if they are not friends with the person. The only exception to this rule would be if the person has their pictures or status updates set so only friends can see it. But how do I make it so no one can see those that are set to public? Sometimes I will like a photo from a facebook page or even comment on one and my friends see that I liked or commented on that photo but I don't want them to. How do I make it so that they can't see when I do that?

Well you might go to setting and do the privacy as only me an see how it works
