Press button , picture appears!

How to make a button that , once it will be pressed it will activate a material/picture and then once pressed on a different button it will deactivate?
I want to create a map preview with this.

Write a script for it. It's like 2 lines of code.

Activator code:

1. public GameObject myPicture; //set a reference in the inspector.
2.  
3. void OnClick()
4. {
5. myPicture.SetActive(true);
6. }
