Did your Twitter timeline's custom wallpaper just disappear on you? No need to panic, there's nothing really wrong There is no widespread Twitter bug. Actually, yes do panic because since it's not a bug, it means there's nothing to be fixed. In a still unexplained move, Twitter removed custom background images and design from your profile and home timeline page. Fear not, it hasn't completely disappeared into nothingness. You can still see them, but only if you're viewing individual tweets and nowhere else in the Twitterverse.
