i've got the solution. I got a free plugin for file browser . C# File Browser in Asset Store.
1 .For File browser code please refer Accessing local system ( File Browser ) in Unity answers.
2.Code for uploading image

hello, what are the steps which you follow to do the upload?
hey thank for your great help but i have simple question what is c_global?
public Texture texNotFound;
private string filelocationinput = "";
void OnGUI ()
{
filelocationinput = GUI.TextField (new Rect (10, 10, 128, 20), filelocationinput);
if (GUI.Button (new Rect (2, 10, 128, 32), "Choose Avatar!")) {
StartCoroutine(LoadTexture ());
}
}
IEnumerator LoadTexture ()
{
WWW www = new WWW ("file://"+filelocationinput);;
yield return www;
Texture avatarImage = null;
if (www.error == null && www.texture != null) {
avatarImage = www.texture;
}
else {
avatarImage = texNotFound;
Debug.Log ("Texture not found");
}
renderer.material.mainTexture = avatarImage;
}
}
something like this work. attach a material to the object you want to have the avatar texture on.
