To make photos private on Facebook, browse to the privacy settings page, and then choose to edit privacy settings to include photo albums and videos. It is also possible to fine-tune the settings for each album.
To start the process, go to the privacy settings page. The default setting is to allow everyone with a Facebook account to see the photos, but to change the photo settings to private, choose the Custom option, and then choose the Customize Settings option.
On this page, it is possible to customize the privacy settings. On each photo album, the Posts By Me setting is the default. This is where it is possible to change the privacy and adjust other settings. There are options that allow some areas of a Facebook profile, such as a website, remain public, but personal posts, such as photos, have restrictions. After updating the settings, choose the option to edit privacy settings for existing videos and albums.
Here, it is possible to set privacy to only friends and to add a watermark. Other suggestions for Facebook photos from experts include for generic images, such as buildings or nature, share with all, unless there is a copyright. If the picture is of friends, share with only friends or friends of friends. If there are photos of children, ask the parent for permission, and then share with only friends.
