User blog comment:Brandon Rhea/Wiki Modernization Stage Two: Page and Article Headers/@comment-5091911-20170419085914

I have a question about the heading. The image displayed on the right appears locked, and how does one change it? On Disney Wiki we often change our theme designs to honor movie releases, holidays and special events. When I change the design of the logo and the color of the header it stays the same until I publish it. Being unable to see how the header looks before I publish it bothers me.
