Users can upload a long horizontal image -- or "header" -- that resembles the cover photo concept currently used on Facebook and Google+. Only, existing profile avatars are embedded in the center of the header.

The header might be similar to other social networks' concepts, but there are a few things to consider before redesigning your profile. Here are a few tips.
1. Selecting an Image
Original image size cannot exceed 1252×626 pixels (with a max file size of 5MB). Twitter does not specify a minimum size, but anything smaller than 640 pixels-wide will appear poor quality.
The header image is a horizontal bar, so any landscape-oriented photo will look better than a portrait (vertical) photo. Although you can resize the image, it doesn't appear to align 100% accurately.
2. Text Against Background
Your new Twitter bio displays in a light-colored font, making the text difficult to read when paired with a light photo. Busy patterns will also distract from the text, so find something simple, at least on the bottom part of the image.
Here's what your header looks like when you choose a light, distracting image.
Instead, choose a header image that contrasts with the font color. A darker photo makes your bio stand out, easy to read for other users. Look at how much better this version reads, in comparison to the photo above.
3. Different Devices
Keep in mind that the new design does not look the same across all devices. The mobile app for iPhone is slightly different. Users see a full Twitter profile in two parts: one shows the user's avatar and handle, and a swipe to the right reveals the user's bio. The iPad displays all on one page, like the desktop.
If you decide to get creative with your header image and newly placed avatar, you might decide whether you want it to look as it should on the app or desktop.
For example, Andrew Tully's avatar aligns perfectly when viewed on the desktop.
However, his header image and avatar do not produce the same optical illusion on the mobile app.
Remember, you still need an avatar. Many users might only view Twitter profiles via third-party apps like TweetDeck or HootSuite. Though creative displays might make sense when paired with your header image (e.g. a picture of your elbow), they could confuse your followers, who might not be viewing your profile on Twitter.com.
