Even if you don't want to pick up Twitter's latest updates, you can still set a header image from the desktop. Head to on Twitter.com. Then, scroll down to the Header option in the "Customize your own" section. Twitter suggests minimum dimensions of 1252 x 626 pixels and a maximum file size of 5MB; in our own tests, however, we were able to upload smaller images via the mobile apps.

Once you add a header from either the mobile apps or via Twitter.com, your updated profile page on the Web will sport a header photo at the top of the page for all to see, with your regular profile picture centered inside it. Just below your regular profile picture, your bio, location, and site link are listed as an overlay on the header image.

Even though these mobile and Web changes aim for a unified look across all devices, those using Twitter.com still have one extra perk mobile users do not: background images. While these don't show up on Twitter's array of apps, the option remains to upload a background photo or choose one of Twitter's wallpaper designs.

You can download the updated Twitter apps for free or from .
