title: Ionic 3: ion-img not loading in ion-list
body: <p>I have a pretty basic image list using <code>[virtualScroll]</code> and <code>ion-img</code>. An array named <code>album</code> is used as the source of the list.</p>
  
  <pre><code>&lt;ion-list [virtualScroll]="album"&gt;
     &lt;ion-item *virtualItem="let image"&gt;
        &lt;ion-thumbnail item-start&gt;
           &lt;ion-img
           [src]="image.nativeURL"
           (click)="photoViewer.show(image.nativeURL, image.name, { share: false })"&gt;
           &lt;/ion-img&gt;
        &lt;/ion-thumbnail&gt;
        &lt;p&gt;
           &lt;b&gt;{{ image.name }}&lt;/b&gt;&lt;br /&gt;
           {{ image.size | filesize }}&lt;br /&gt;
           {{ image.modificationTime }}&lt;br /&gt;
        &lt;/p&gt;
        &lt;ion-icon name="close" item-right (click)="deleteImage(i)"&gt;&lt;/ion-icon&gt;
     &lt;/ion-item&gt;
  &lt;/ion-list&gt;
  </code></pre>
  
  <p>The list scrolls smoothly, but the images don't always load, despite all of them are local images. Some do, some don't, apparently randomly. This is what it looks like:</p>

  <p>Why?</p>
