One of the features introduced with the new HU interface, is the ability to personalise your profile by adding a banner image that will appear across the top of your profile.
Here's how to do it and perhaps share something more about you, where you live, what you like, etc:
support.healthunlocked.com/...
I cropped my image out of a digital photo using GIMP, but the new HU site will allow you to upload an image larger that the recommended size and then move the image to how you want it displayed before you save it.
While HU recommend a banner image of over 1,170x250pixels, I was advised by HU that double this (2,340 x 500) looks great on a Retina display, though that will of course add to the loading time for anyone visiting your profile. You can visit another member's profile by clicking on their username.
