try {
	URL url = new URL(SERVER_POST_URL);
	HttpURLConnection c = (HttpURLConnection) url.openConnection();
	c.setDoInput(true);
	c.setRequestMethod("POST");
	c.setDoOutput(true);
	c.connect();

	OutputStream output = c.getOutputStream();
	bitmap.compress(CompressFormat.JPEG, 50, output);
	output.close();

	Scanner result = new Scanner(c.getInputStream());
	String response = result.nextLine();
	Log.e("ImageUploader", "Error uploading image: " + response);

	result.close();
} catch (IOException e) {
		Log.e("ImageUploader", "Error uploading image", e);
}
