In your Edit Profile
page you have a Gear icon
on the top that opens the Profiles Settings
There you can turn on Advanced Profiles
to have more information boxes to fill About
You also have Multiple Profiles
. With this you can have more profiles other than your Default Profile
which is Public
. In a new Profile you can increase Visibility
by adding your connections to it. Otherwise no one will see this profile and its information.
It let's you have private profiles
with more information, or just different than your default/public profile.
You can add/change everything, including name and picture.
For example: You can be "Mark" in your Default Profile, but in a second profile that you show only for very trusted friends you can put "Mark Zuckerberg". And put your real picture too.
You can make profiles in layers of privacy or for different groups of interests.
