Мой код:
public class MainActivity extends ActionBarActivity {
String URL1 = "http://cs619925.vk.me/v619925510/1b82b/0nTm-Pj0ABM.jpg";
String URL2 = "http://8tracks.imgix.net/i/000/955/740/87318.original-8382.jpg?rect=128,0,768,768&q=65&sharp=15&vib=10&fm=jpg&fit=max&w=200&h=200";
String URL3 = "http://a400.idata.over-blog.com/300x225/1/89/70/64/Autres-images/smiley-face-on-beach.jpg";
@Override
protected void onCreate(Bundle savedInstanceState) {

}
public class DownloadImagesTask extends AsyncTask<ImageView, Void, Bitmap> {

}
protected void onPostExecute(Bitmap result) {
