title: Load images from disk cache with Picasso if offline
body: <p>I have some images that I download from different web sites when the app starts, by doing this:</p>
  
  <pre><code>Picasso.with(context).load(image_url).fetch();
  </code></pre>
  
  <p>Now, suppose the user closes the app and turns offline. When the app starts again, Picasso display the images in this way:</p>
  
  <pre><code>Picasso.with(ctx).load(image_url).placeholder(R.drawable.ph).into(imageView);
  </code></pre>
  
  <p>The problem is that some images are loaded from the disk cache (yellow triangle in debug mode), and for the others Picasso shows the placeholder.</p>
  
  <p>Why? I'm expecting that every image is loaded from the disk cache.</p>
