It would be very useful for making our own maps work.
Any suggestions?
Thanks
Apparently, it is not possible to add custom images locally. Read the documentation about background maps. You can use the two built-in types of background maps or pull them from a Web service.
You can create custom shape files (a pair of files) that are used for boundaries, though. They can be stored with the data table or in the default folder for built-in shapes.
@Mark_Bailey is quite right. But you 'can' add any image as a watermark to a graph. This may or may not be what you are after, and if you do this you have the responsibility to take care of the correct registration of the map with the axes. I didn't do this in the example below.
