title: Efficient way to load large number of same image in ReyclerView
body: <p>I developed a chat app. It uses RecyclerView to show chat info. It's exactly like facebook messenger. </p>
  
  <p>My problem is, loading the image of user I'm chatting to takes time, and make the app slow when there's large number of chat messages.</p>
  
  <p>I'm using picasso to load image.</p>
  
  <pre><code>Picasso.get()
                      .load("https://domain/images/profile_picture/" + otherImage)
                      .networkPolicy(NetworkPolicy.OFFLINE)
                      .transform(new CircleTransform())
                      .into(imageView, new Callback() {
                          @Override
                          public void onSuccess() {
  
                          }
  
                          @Override
                          public void onError(Exception e) {
  
                              int placeHo;
  
                              if(otherGender.equals("female"))
                                  placeHo = R.drawable.ic_female_color;
                              else
                                  placeHo = R.drawable.ic_male_color;
  
  
                              Picasso.get()
                                      .load("https://domain/images/profile_picture/" + otherImage)
                                      .error(placeHo)
                                      .transform(new CircleTransform())
                                      .centerCrop(Gravity.TOP)
                                      .into(imageView, new Callback() {
                                          @Override
                                          public void onSuccess() {
  
                                          }
  
                                          @Override
                                          public void onError(Exception e) {
                                              Log.v("Picasso","Could not fetch image");
                                          }
                                      });
                          }
                      });

  <p>Is there any efficient way to show the image? as it's showing the same image(user profile picture).  </p>
