Twitter introduced a feature similar to Facebook's "Cover Photo" that allows users to post a large personal picture to their profile page.
It also updated the apps for using Twitter on mobile devices such as iPhones and iPads as well as phones running Android.
Users can now add large photos that will appear above their tweets on their profile page, a feature Twitter is calling the "Header Photo."
But the Header Photo is hardly innovative. Facebook introduced something similar called the Cover Photo back when it announced its new Timeline profiles late last year. Since then, more websites have been adopting similar looks, including Google+ and LinkedIn.
