Sprite Rendering

(I'm using Unity 5.5)

Hi everyone,

I am writing a mobile game that uses many different icons at any given time, so I'm loading all my images at runtime to reduce size and compilation time loading. I can't seem to get my sprites to load currently, can anyone tell me what is wrong with my code?

Thanks! Here's the necessary portions:

     public GameObject _enchantment1icon;
     public GameObject _enchantment2icon;
     public GameObject _gem1icon;
     public GameObject _gem2icon;
     public GameObject _mog1icon;
     public GameObject _mog2icon;
 
 public void loadCharacter(Text character){
         _statsName.text = character.text;
         _characterStats.gameObject.SetActive (true);
         _playButton.gameObject.SetActive (true);
 
         switch (character.text) {
         default:
             _enchantment1icon.GetComponent<Image> ().sprite = Resources.Load<Sprite> ("images/enchantment1icon.png") as Sprite;
             _enchantment2icon.GetComponent<Image> ().sprite = Resources.Load<Sprite> ("images/enchantment2icon.png") as Sprite;
             _gem1icon.GetComponent<Image> ().sprite = Resources.Load<Sprite> ("images/gem1icon.png") as Sprite;
             _gem2icon.GetComponent<Image> ().sprite = Resources.Load<Sprite> ("images/gem2icon.png") as Sprite;
             _mog1icon.GetComponent<Image> ().sprite = Resources.Load<Sprite> ("images/pawn1default.png") as Sprite;
             _mog2icon.GetComponent<Image> ().sprite = Resources.Load<Sprite> ("images/pawn2default.png") as Sprite;
             break;
         }
 
     }

As a note: I am pulling images in other parts of my code for buttons, and that is working. So the pathways are certainly correct, my confusion just comes from loading sprites from resources.
