If I have a folder called “Factoid Images” that is located in Textures/Factoid Images

How can I change that image to a new image from that folder with each:

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class FactoidManager : MonoBehaviour {

	public Image factoidImagePlaceholder;
	public Sprite[] gallery;	//Store Factoid images in here
	public int i = 0;	//Will Control where in the array we are


	public Text factoidScreenText;
	public TextAsset factoidText;
	public string[] factoidLines;


	public int startLine;
	public int endLine;


	void Start(){
		factoidImagePlaceholder.enabled = false;
		if (factoidText != null) {
			factoidLines = (factoidText.text.Split ('

'));
}

		if (endLine == 0) {
			endLine = factoidLines.Length - 1;
		}
	}

	void Update () {
		factoidImagePlaceholder.sprite = gallery*;*

If you don’t want to reference them in the inspector then i think you have to put the entire folder into a Resources folder. Then you can load them with Resources.Load<Image>("Factoid Images/imgName");
