            conn.setReadTimeout(READ_TIMEOUT);

			BitmapFactory.Options opt = new BitmapFactory.Options();
			opt.inPreferredConfig = Bitmap.Config.RGB_565;
			opt.inPurgeable = true;
			opt.inInputShareable = true;
               
            bitmap = BitmapFactory.decodeStream((InputStream) conn.getContent(), null, opt);
