You can add a Header and footer to every page in every space (if you are a Confluence admin) by going to the global Settings (top right-hand corner) then in the Look and Feel section of the left-hand menu select Header and footer.

You'll find instructions for adding an image using wiki markup here: Confluence wiki markup syntax.
