If you logged into your Twitter account on the web today, you might have noticed something new. If you had previously uploaded a custom wallpaper image or just used one of Twitter's available designs, you'll notice it no longer appears as the background of your Twitter homepage. A Twitter spokesperson told Engadget, "we're removing background images from the home and notifications timelines on web for all users. Now, background images are only available where logged-in users will see them publicly (Tweet pages, list pages and collections pages)." The images have been replaced with a blank background with a very slight hint of blue. By removing the background images on homepages and feeds, Twitter is able present a cleaner more unified look to new users. It also means that there's the chance that in the future, background wallpapers might disappear all together. So you might want to get used to the bland blueish-white background.
