title: Display background image in Neo4j browser
body: <p>Some nodes in my graph database have a property which contain a URL to an image. I wanted to use Neo4j browser's style sheet functionality to display that image as the background image of a node.
  My .grass file looks like this:</p>
  
  <pre><code>node {
    diameter: 40px;
    color: #DFE1E3;
    border-color: #D4D6D7;
    border-width: 2px;
    text-color-internal: #000000;
    caption: '{name}';
    font-size: 10px;
    background-color: #00aaee;
  }
  
  node.Actor {
    color: #AD62CE;
    border-color: #9453B1;
    text-color-internal: #FFFFFF;
    background-image: url('{image}');
  }
  </code></pre>
  
  <p>After I uploaded the file, the line <code>background-image: url('{image}');</code> gets converted to <code>background-image: url({image});</code> (missing apostrophes). No image is shown in the browser.</p>
  
  <p>What am I doing wrong?</p>
