Heres a simple Macro for umbraco to allow you to update a logo or image on a page depending upon which page you have selected. You can use it to dynamically update images based upon content etc.
Here we check to see if the current page nodename is home (i.e. homepage) and set it to one thing, otherwise set it to something else. Obviously you can add as many conditions as you like.
