Choose picture in Account settings → Profile picture opens the image picker used across Magpie: pick a picture you have already uploaded, or upload, drop or paste a new one, and it becomes your profile picture straight away. The page no longer shows an open upload form with a Cancel button.
Use Google picture and Remove picture each have their own row, so Remove picture is no longer directly under the button that saves a new one. Removing a picture still asks first, and the picture stays in Your images.
