Cant load image into my game

I want to import an image at runtime into my game from a folder. There is a button, which opens the Editor Utility Open Folder Dialog so you can choose the folder where an image with the name “1 - mid” must be inside. After Choosing the Folder, the image “1 - mid.*” will be added on a new plane.
To import the image to the plane I’m using the following code:

using UnityEngine;
using System.Collections;
using System.IO;
using UnityEditor;
using UnityEngine.UI;

namespace ImportClass {
	public class ImportPack : MonoBehaviour {
        IEnumerator LoadTexture (FileInfo newPath)
			WWW www = new WWW ("file://"+newPath);;
			yield return www;
			Texture NewImage = null;
			ButtonGameObject.GetComponent<Renderer>().material.mainTexture = www.texture;

Actually everything works fine when I start use this. But when I choose the Folder to import, it shows a questionmark image on the Plane…

This is the actual image that I want to show ingame…


Can someone tell me why it shows the questionmark instead of the chosen image?

i’d say the problem is in this line

WWW www = new WWW ("file://"+newPath);;

where you are adding FileInfo to the string

“Note: When using file protocol on Windows and Windows Store Apps for accessing local files, you have to specify file:/// (with three slashes).”
