Twitter is getting an overhaul.

The site announced major changes on Tuesday with redesigned profiles, updated apps and a sharper focus on pictures.

The redesign was unveiled by Twitter’s CEO Dick Costolo on NBC’s Today Show Tuesday morning.

A new emphasis on profile pages will allow people to upload a header photo that will run across the top of the screen. The banner-like image is reminiscent of Facebook’s cover photos on its timeline.

A person’s avatar will also be a prime focus as it gets moved from the left hand corner to front and centre of the page.

“New profiles also help you get to know people better through their pictures,” Twitter released in an online statement Tuesday.

A revamped photo stream will appear below a person’s most recent Tweets on iPhone, Android and iPad. “Swipe through the stream to see the photos other users have shared or tap any thumbnail to view their photos in full screen,” Twitter says in a statement on its blog.

The new launch focused on updating and changing Twitter’s mobile apps for iPhone, iPad and Android. The changes seen on Twitter.com profiles will also be included in the app releases. Any images uploaded to the site will appear the same across all platforms – phone, tablet or computer.

The iPad app was one of the biggest changes as it has been rebuilt “from the ground up to make it fast, beautiful and easy to use.”

Twitter said the iPad app will allow tweets to “come alive” as they are expanded to reveal photos, videos and web page summaries with a single click. For Android users, the special pinch-to-zoom feature will allow them to get more interactive.

Twitter featured a number of celebrities and news outlets in its blog that have already made the switch.

Ryan Seacrest launched his new profile with a header photo of himself surrounded by Randy Jackson, Mariah Carey, Nicki Minaj and Keith Urban – the newest American Idol judges, according to a tweet by Seacrest. Seacrest’s solo picture is taken from this image and appears beside his tweets.

Seacrest appeared on the Today show with Costolo to announce the big changes.

The Today Show itself displayed its Twitter profile change with before and after images on the show’s website.

Twitter users can choose to make the switch to the new profile starting Tuesday by uploading a header in the design tab of their account settings, communication team member Robert Weeks said in an email to CTV News.

Apps are available for download on Tuesday.
