Unity3D - Issue when trying to apply ".byte" file as an object texture

Question

I am creating a C# script that applies an imported texture to a plane (Game Object) when the program starts. For that, I am copying the user choosen image to the assets folder. Then I change it to .byte extension, that's because I am using TextAsset to read and set the object texture.

Now what i consider that is failing is the texture Load, this is the full script code:

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

public class setplant : MonoBehaviour {
    GameObject plant;
    void Start () {
        plant = GameObject.Find("plant");
        string currentdirectory = System.IO.Directory.GetCurrentDirectory();
        string pathconfig = (Path.GetFullPath(Path.Combine(currentdirectory, "..\\Pick_And_Build\\Launcher\\Launcher\\bin\\Debug\\tempfiles\\"))+"instanciateprogram.dat");
        StreamReader reader = File.OpenText(pathconfig);
        string img = reader.ReadLine();
        reader.Close();
        string textureresourcepath = Directory.GetCurrentDirectory() + "\\Assets\\" + Path.GetFileNameWithoutExtension(img) + ".byte";
        if(!File.Exists(textureresourcepath))
            File.Copy(img, textureresourcepath);
        TextAsset imageasset = UnityEditor.AssetDatabase.LoadAssetAtPath(Path.GetFileName(textureresourcepath), typeof(TextAsset)) as TextAsset;
        Texture2D tex = new Texture2D(2, 2);
        tex.LoadImage(imageasset.bytes);
        plant.GetComponent<Renderer>().material.mainTexture = tex;
    }
    void Update () {
    }
}

Note: The image is copied to the Assets folder so the directory system is working.

The output for this is just a Plane with the Default-Material instead of the image texture-based material. Any tips?

SOLUTION

It was a stupid bad extension issue. It is not .byte ... ".bytes" is the correct one. Thank you anyway for the people that tried to help me.
