Changing a sprite in image canvas VIA C# script

A quick question, if I want to change the source image of an "Image" component through a script, how would I go about that? I am trying to access the source image property but I can't figure out how.

 

I think the easiest method would be to declare public variables and input your image and sprite directly into the inspector:

Code (csharp):

1.  
2. public Image imageToChange;
3. public Sprite newImage;
4.  

Then when you want to change it:

Code (csharp):

1. imageToChange.sprite = newImage;

edit: don't forget to include the namespace of course

Code (csharp):

1. using UnityEngine.UI;

 

You sir or madam are my hero, thanks a ton!
