Log in to your user account.
2Click the Edit Profile button at the top right of the browser window.
The Edit Profile button looks like a gear.

The Design Settings open.
4In the Customize Your Own section, click the Change Background button.
The Change Background drop-down menu opens.

The selected image is uploaded to Twitter, but it may not be visible until the page is saved.

Think carefully about the positioning of your image. It can be a vital part of your design.
8Click the Save Changes button.
The background is saved and becomes visible in the background of the Twitter page.
