Can we send an image to browser via Application.ExternalCall ?

I am bouncing variables back & forth from unity web player to browser, in order to collect facebook user info without using facebook SDK (not very easy to use). I manage to pass rest of the stuff in, but I'm stuck on the screen capture.


var snap = new Texture2D(Screen.width, Screen.height, TextureFormat.RGB24, false);
snap.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
snap.Apply();
var screenshot = snap.EncodeToPNG();
Application.ExternalCall ("PostScore", screenshot)

Can this be done? Cause my current code is not working.

 

Well kind of... After you encode to png, base64 encode it. Then send the base64 string. You can actually display an image in the browser using the base64 string
