title: ImageView refresh with Glide
body: <p>I have one ImageView and one image loaded in it with Glide:</p>
  
  <pre><code>Glide.with(ImageView.getContext())
      .load(url)
      .dontAnimate()
      .placeholder(R.drawable.placeholder)
      .signature(stringSignature)
      .into(new GlideDrawableImageViewTarget(ImageView) {
          @Override
          public void onResourceReady(GlideDrawable drawable, GlideAnimation anim) {
              super.onResourceReady(drawable, anim);
              progressBar.setVisibility(View.GONE);
          }
      });
  </code></pre>
  
  <p>and when I want refresh the image, I run this same code again only with new signature. It's working perfectly, but when new loading is started, the visible image is gone immediately.</p>
  
  <p><strong>Question</strong></p>
  
  <blockquote>
    <p>Is possible keep the image in ImageView and replace it after new image is downloaded?</p>
  </blockquote>
