Displaying a simple Image

[ohmi]

Please excuse my noob question,

Is there something similar to InformationManager.ShowInquiry that takes a Picturebox?

I am working on a mod that allows to save and display a political map of calradia, like this:

So far I got it to be saved dynamically to my mod folder, but I don't really know how to get it in the game.
Any advice is appreciated.
