this.gameObject.GetComponent<GUITexture>().texture = GetPic(Application.dataPath + @"/Pictures/1.jpg");
}

Texture GetPic(string filePath)
{
Texture temp = new Texture();
FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read);
byte[] array = new byte[fs.Length];
fs.Read(array, 0, (int)fs.Length);
Texture2D _tex2 = new Texture2D(128, 128);
_tex2.LoadImage(array);
temp = _tex2 as Texture;
return temp;
}
// Update is called once per frame
void Update () {

}
