private void imageDownload(final String imgUrl){
		final String tempFileName = System.currentTimeMillis() + ".png";
		new Thread(new Runnable() {
			URL url;
			@Override
			public void run() {
				// TODO Auto-generated method stub
				try {
					url = new URL(imgUrl);
					InputStream is = url.openStream();
					Bitmap bitmap = BitmapFactory.decodeStream(is);
					saveFile(bitmap, tempFileName);
					handler.sendEmptyMessage(GETPIC_OK);
					is.close();
				} catch (MalformedURLException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				} catch (IOException e) {
