Are you referring to the images on the Ribbon or the Quick Access Toolbar?
If the Ribbon then you would need to customize the Ribbon in order to change
an image. This requires XML knowledge.
If the QAT, you could create a macro that executes the command, add the
macro to the QAT, and then change the image.
Customizations such as these have changed a lot from previous versions of
Office.
