title: How to display ImageInput src in another component on react-admin?
body: <p>I'm using react-admin and I want to display the chosen image in another component.</p>
  
  <p>I have already an image on my Edit screen. When I select a new one with ImageInput, I'd like to display it in my <code>&lt;Poster /&gt;</code> component and change the existing image with a new one.</p>
  
  <pre><code>&lt;Poster id="poster" {...props} source="card_image_path" 
  label="resources.cards.fields.card_image_path" /&gt;
  
  &lt;ImageInput id="imageInput" source="images" accept="image/*"&gt;
    &lt;ImageField source="src" title="title" /&gt;
  &lt;/ImageInput&gt;
  </code></pre>
