Earlier this week, Twitter announced a new addition to Twitter profiles: “header photos.” Similar to Facebook’s Timeline cover photo, Twitter’s header photo is another image to better portray and express yourself to your Twitter followers. When you add your header photo, it will appear on your Twitter profile when viewed on mobile apps for iPad, iPhone and Android or twitter.com
To add a header photo, visit your Twitter “Settings.” Go go “Design” tab and add an image that is 1252x 626px as your header.
