Like Facebook & Google+, now Twitter also provides frontend profile editing features. Now instead of going to Twitter settings and navigating to profile edit section you can easily edit your profile information like your profile photo and bio direct from your Twitter’s profile page.
How it works ?
Login to your Twitter account, open your public profile and click Edit Profile button.
Now click small pencil button for changing your header image and profile photo. Other than this you can change your display name, bio and location simply by putting your cursor there and using your keypad.
