Changing a sprite in code

[ENAY]

Ok, stupid question alert. How do I change a sprite into another? In code all I want to do is choose another sprite in the atlas.

Put simply, I want something like this.

MyNGUIMenu.GetComponentsInChildren<UISprite>()[0].image = "image2";


This is for a character select screen, I have my window, multiple faces in the atlas, just need to find that last piece of the puzzle to change the face.

You will want to change the sprite name.

UISprite mySprite.spriteName = "newSprite";

I tried spritename earlier and nothing happened. So I tried it again and now it magically works.   
I am sometimes baffled by Unity sometimes. 
Thanks for that dlewis, feels really embarrassing asking such a stupid question but hey, I have no shame.
