Just like the cover image on your Facebook and Google Plus account, it seems that Twitter already has one. So far, I might have seen some special Twitter users having some header like image on top of their profile pages and I still haven’t set up my account to have that. By tomorrow, if you don’t upload a header photo, you will end up seeing the default grey image on your profile and that’s not good looking but don’t worry, it doesn’t seem to be a large consequence anyway. It is somewhat their recommendation or encouragement for you to do it.
