Accessing image source from script

Hi guys. So I've been messing with the new UI for a few hours and I'm trying to make an inventory system. So far everything has been going smoothly except for one very simple thing. I can't seem to find the name of the property that corresponds to the image source, which I'm trying to access via a script. I tried different things such as "image", "imageSource", "texture" but so far no luck. Here's the bit of code I'm using, although I don't think it's going to help much

Code (CSharp):

1. GameObject newItem = (GameObject)Instantiate(itemPrefab, Vector3.zero, Quaternion.identity);
2. newItem.transform.parent = grid;
3. newItem.GetComponentInChildren<Image>().image = item.logo;

EDIT: Nevermind, I found it. It's simply "sprite"
