Mark fireDude67's answer as correct but here is how it should have properly been written

using UnityEngine;
using System.Collections;

public class Crosshair : MonoBehaviour {

    public Texture image;

void OnGUI() {
  GUI.DrawTexture(new Rect(Screen.width / 2, Screen.height / 2, image.width, image.height), image);
}
}

Just make a new csharp file named Crosshair and that will do the trick. fireDude was just missing a } and a )

First you will need a `Texture` to use as the crosshair image:

public Texture image;

Or in JavaScript:

var image : Texture

Then you will need to draw it:

void OnGUI() {
     GUI.DrawTexture(new Rect(Screen.width / 2, Screen.height / 2, image.width, image.height);
}

JavaScript:

function OnGUI() {
     GUI.DrawTexture(new Rect(Screen.width / 2, Screen.height / 2, image.width, image.height);
}

copy and paste this into a JavaScript:

var image : Texture;

function OnGUI() {
     GUI.DrawTexture(new Rect(Screen.width / 2, Screen.height / 2, image.width, image.height);
}

C#:

public Texture image;

void OnGUI() {
  GUI.DrawTexture(new Rect(Screen.width / 2, Screen.height / 2, image.width, image.height);
}
