In Facebook,You can set the privacy of each photo you uploaded.You can make the photo visible to all by setting its privacy to public, only to friends by selecting friends and even to some particular Facebook group.But the cover photos in Facebook are public by default.That means all the cover photos are visible to everyone.But now you can change the privacy of your previous cover photos.Last time when I changed my Facebook cover photo, a tip shown up displaying text – “Now you can change who can see your old cover photos – just go to your Cover Photos Album.You can change the privacy of each one.”
So now Facebook allows you to set the privacy of your old cover photos .In order to change the privacy options of your previous cover photos, navigate to photos, your photos and move the pointer over your any cover picture.Cover photos link will appear .Click on it and your cover photos gallery will open.
Open the Photo whose privacy you want to change.For example, I want to make one of my cover photo visible only to friends, so I will choose Friends from privacy list options.
Similar to this, You can set the privacy of each one of your old cover photos.This option was not available before and Facebook has made this change just few days back.All the cover photos were public and hence visible to everyone by default.
One thing worth mentioning is that your current cover photo is still public and you cannot change its privacy options.Current Cover photo is visible to everyone and you can set visibility only of old cover photos.
