Adding Cover Photo on your Twitter Profile

Have you ever seen his layout before?
This is Twitter's newest feature > Heading Photo

The header photo is different from your Twitter profile picture, which appears inline when you send a tweet. Your profile picture is an icon; the header photo is a background image.
Once you upload a header photo, that image is visible to others accessing your Twitter page via iPad, iPhone or Android application as well as via twitter.com

To upload a header photo to your Twitter page:

1. Click the 'gear' icon in the top-right of your twitter.com page and select "Edit profile."
2.  Then, from the menu on the left, click "Design" and scroll to the bottom. Under "Customize your own,"
3. Then, upload your favourite photo (must less than 5MB)
4. And the last, click "Save changes", Finish!

It must be nice Twitter profile of you now ;)
