Images or custom Code in calculator

Hello,

I am looking to create a Map region selector inside the calculator.

The simplest version of what I am trying to achieve is that by choosing a region from a drop down menu I can display an image of that region in for example the summary area of the calculator.

Is such a thing possible?

I understand this is not built in the calculator,
but perhaps there is a possiblity to add custom code to the calculator, so
when a selection Is made, I can display just an image to a certain area.

-Thanks.
