Updating Taken Pictures in Game

Hey all! I am using the following code to create usable .png files in my resources folder which are being called to a texture inside of my game.

using UnityEngine; using System.Collections; using System.IO;

public class SnappitPictureTake : MonoBehaviour {

 private int count = 0;


 void Update()
 {
     if (Input.GetKeyDown("k"))
         StartCoroutine(ScreenshotEncode());


 }
 
 IEnumerator ScreenshotEncode()
 {
     // wait for graphics to render
     yield return new WaitForEndOfFrame();
     
     // create a texture to pass to encoding
     Texture2D texture = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
     
     // put buffer into texture
     texture.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
     texture.Apply();
     
     // split the process up--ReadPixels() and the GetPixels() call inside of the encoder are both pretty heavy
     yield return 0;
     
     byte[] bytes = texture.EncodeToPNG();
     
     // save our test image (could also upload to WWW)
     File.WriteAllBytes(Application.dataPath + "/../Assets/Resources/testscreen-" + count + ".png", bytes);
     count++;
     
     // Added by Karl. - Tell unity to delete the texture, by default it seems to keep hold of it and memory crashes will occur after too many screenshots.
     DestroyObject( texture );
     
     Debug.Log( Application.dataPath + "/../Assets/Resources/testscreen-" + count + ".png" );
 }

}

The issue, however, is that these pictures are supposed to update in game over each other when a picture overwrites a previous one. They do eventually do such, but only if you exit the unity menu and return to the game, or otherwise restart the game.

Any way that I can force the game to call upon the newly updated file, rather than wait for a refresh? I'd like to allow the photos to be viewed in game and be the actual photos to be viewed, rather than otherwise.
