In this section of the profile, this is a very nice and clean area for creating a new password. Simply type in your current password and the new passwords in the corresponding fields and click the "Change Password" button. It's that simple, your password is changed.
On the bottom left hand side of each picture there is a link "Set Profile Photo", with exception to the one currently set as the profile photo.

To remove the current profile photo simply click, "Current Profile Photo".
In the Profile sites section there will be a list of sites you have access too. For each site, there are corresponding links to view or sign-in to the other sites.
