Anyone who uses your Ning Network can see the albums you create. There are, however, a number of different privacy settings for the photos you upload. You can change these default setting by clicking on your “Settings” link in the box on the right column to allow anyone, just your friends, or just you to see your photos. You can also override this setting as you upload each photo.
Once you’ve chosen the default Privacy Settings you want, make sure to scroll down and click “Save” to save your changes.
