I created an album and marked the privacy setting as “only me.” If I change the setting to allow the alum to be visible to “friends,” will my album appear in my friends newsfeed (ie, “Grace posted 20 pictures 10 days ago”) because it will then be fresh, unseen news to my friends? What if I wait awhile, say, a month, before changing the privacy setting - will that make it impossible to appear because it’s terribly old/un-newsworthy, or more likely, because then the post will be something newly available/visible content for my friends?
