Have you noticed the changes to your Google+ Profiles yet? The navigation is now flexible and there is some enhancements to video and images sharing. You can personalise where the navigation sits.
You will need to add a new profile pic image. Very similar to the Facebook timeline update recently. The new Google Plus image size is 940 x 180 pixels. The image tool will allow you to crop to the correct size if larger, but there is a minimum of 940 wide.
You can also use one of the alternative templates that display five images, similar to the previous layout.
