In previous versions of SDL Tridion, you could add a logo to the Content Manager Explorer by updating the CSS (see [my example on TridionDeveloper][1]).

Specifically, you could add a `background-image` to these CSS selectors:

    .tridion .abouttridion .button,
    .tridion .abouttridion .button.mouseover,
    .tridion .abouttridion .button.mousedown

It looks like the .abouttridion class has been replaced with the personal information center.

I've left a comment on [SDL Documentation][2], but what element would you recommend for adding a logo-type image to the interface?
