title: How do I render a jpg image using ARKit ARSKViewDelegate?
body: <p>I'd like to render a jpg image as a 2d rectangle floating in space. Using the SpriteKit example - how do I return a jpg image from the <code>ARSKViewDelegate</code>?</p>
  
  <p>The demo returns a <code>SKLabelNode</code> - is there a Node class that would be appropriate for a jpg image that I would fetch from the network, maybe a <code>UIImage</code>?</p>
  
  <pre><code>func view(_ view: ARSKView, nodeFor anchor: ARAnchor) -&gt; SKNode? {
      // Create and configure a node for the anchor added to the view's session.
      let labelNode = SKLabelNode(text: "")
      labelNode.horizontalAlignmentMode = .center
      labelNode.verticalAlignmentMode = .center
      return labelNode;
  }
  </code></pre>
