How to check the current sprite in the image source? Unity 4.6beta20

Hey, so I'm making an inventory and I need to check if the image source in the image component is "Blank_Icon" which is an actual sprite. So I added the Blank_Icon sprite to the Resources and the code goes like this:

 public void AddItemToInventory(string itemName)
     {
         for (int i = 0; i < 2; i++) {
             if (invIcons[i].GetComponent<Image>() == Resources.Load("Blank_Icon")) {
                 print("Found an empty space!");
                 break;
             }
         }
     }

This doesn't work thought so how could I make it work? Thanks!
