Send image to a webserver in Android or Java

This is very helpful example to send image on webserver.

This is source code from above link...
Is this very helpful. I used this technique in my Android code.

// create a bitmap variable before anything;

private Bitmap bitmap;

// variable to set a name to the image into SD card;
// this variable, you have to put the path for the File, It's up to you;

public static String exsistingFileName;

// sendData is the function name, to call it, you can use something like sendData(null);
// remember to wrap it into a try catch;

public void sendData(String[] args) throws Exception {
try {

HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();

// here, change it to your php;

HttpPost httpPost = new HttpPost("");
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
bitmap = BitmapFactory.decodeFile(exsistingFileName);

// you can change the format of you image compressed for what do you want;
//now it is set up to 640 x 480;

Bitmap bmpCompressed = Bitmap.createScaledBitmap(bitmap, 640, 480, true);
ByteArrayOutputStream bos = new ByteArrayOutputStream();

// CompressFormat set up to JPG, you can change to PNG or whatever you want;

bmpCompressed.compress(CompressFormat.JPEG, 100, bos);
byte[] data = bos.toByteArray();

// sending a String param;

entity.addPart("myParam", new StringBody("my value"));

// sending a Image;
// note here, that you can send more than one image, just add another param, same rule to the String;

entity.addPart("myImage", new ByteArrayBody(data, "temp.jpg"));

HttpResponse response = httpClient.execute(httpPost, localContext);
BufferedReader reader = new BufferedReader(new InputStreamReader( response.getEntity().getContent(), "UTF-8"));
String sResponse = reader.readLine();

} catch (Exception e) {

Log.v("myApp", "Some error came up");
