Images of 1 Mg or less can be added to background objects and then stretched to sit behind your Map as part of the visual story.
Personalise your maps to give them a style that reflects the story you are trying to tell and makes the Map come alive.
Create a background object and then Right-click and Add Artwork.
Also, add Artwork to individual objects in the same way. For example icons for parts of the programme you are describing or profile shots for stakeholders.
