Send image to Server

When I send a [] byte converted to String to the server on the server it comes empty or bursts. I do not understand why.

  Bitmap photo = (Bitmap)data.getExtras().get("data");
                    photo = Bitmap.createScaledBitmap(photo, 800, 1422, false);
                    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
                    photo.compress(Bitmap.CompressFormat.PNG, 100, bytes);

                    byte[] imageArray = bytes.toByteArray();

                    String imageAsString = Base64.encodeToString(imageArray, Base64.DEFAULT);

Then to send to the server I do:

private String InsertImage(String url)
{
    HttpClient client = buildHttpClient();
    HttpPost request = new HttpPost(url);
    HttpResponse response = null;
    String responseString = "";

    try
    {
        System.out.println("VOU PARA O SERVIDOR");
        JSONObject jsonObject = this.setHeadersAndbuildJSONObject(request);

        System.out.println("vou levar 1 - " + sessionID);
        System.out.println("vou levar 2 - " + data[0]);
        System.out.println("vou levar 3 - " + data[1]);

        jsonObject.put("SessionGUID", sessionID);
        jsonObject.put("Address", data[0]);
        jsonObject.put("imageAsBytes", data[1]);

        responseString = this.executeRequest(jsonObject, request, response, client);
        System.out.println("VIM DO SERVIDOR " + responseString.toString());

    }
    catch (Exception e)
    {
        System.out.println("ERRO " + e.getMessage());
    }
    return responseString;
}

In system.out you see the variables are all well filled.
