  In the **ElementType** file, the **getSources** method needs to have the *hasThumbs* key set, as follows:
  
  ```
  public function getSources($context = null)
  {
      $sources = array(
          '*' => array(
              'label'    => Craft::t('All assets'),
              'hasThumbs' => true,
          )
      );
  }
  
  ```
  
  In your **Model** file you have to have a **getThumbUrl** method defined, as follows:
  
  ```
  public function getThumbUrl()
  {
      return $this->thumbnailUrl;
  }
  
  ```
  
  This results in a small thumbnail next to the title of your element, as seen in the screenshot:
