How to assign a 2D Texture from Application.dataPath to Raw Image component

Hello guys i am trying to assign a scrrenshot to a Raw Image Component. Here is the code to make a screenshot it works fine :

 using UnityEngine;
using System.Collections;
public class ScreenShot : MonoBehaviour {
     public int resWidth = 2550;
     public int resHeight = 3300;
     private bool takeHiResShot = false;
     public static string ScreenShotName(int width, int height) {
         return string.Format("screenshot.png",
                              Application.dataPath,
                              width, height,
                              System.DateTime.Now.ToString("yyyy-MM-dd_HH-mm-ss"));
     }
     public void TakeHiResShot() {
         takeHiResShot = true;
     }
     void LateUpdate() {
         takeHiResShot |= Input.GetKeyDown("k");
         if (takeHiResShot) {
             RenderTexture rt = new RenderTexture(resWidth, resHeight, 24);
             GetComponent<Camera>().targetTexture = rt;
             Texture2D screenShot = new Texture2D(resWidth, resHeight, TextureFormat.RGB24, false);
             GetComponent<Camera>().Render();
             RenderTexture.active = rt;
             screenShot.ReadPixels(new Rect(0, 0, resWidth, resHeight), 0, 0);
             GetComponent<Camera>().targetTexture = null;
             RenderTexture.active = null; // JC: added to avoid errors
             Destroy(rt);
             byte[] bytes = screenShot.EncodeToPNG();
             string filename = ScreenShotName(resWidth, resHeight);
             System.IO.File.WriteAllBytes(filename, bytes);
             Debug.Log(string.Format("Took screenshot to: {0}", filename));
             takeHiResShot = false;
         }
     }
}

As you see it makes a screenshot and saves it as " screenshot.png" to Application data path.
I need to find this screenshot via code and assign it to a Raw Image component ( normal Image component does not work)

Thank you very much in advance!!
