title: Threejs Change image at runtime
body: <p>I'm showing a 3d obj and applying the texture as jpg.
  but I want to change this image when I click on a button, it is possible and how could I do that?</p>
  
  <pre><code>var loader = new THREE.ImageLoader(manager);
  loader.load('models/obj/dla/dla.jpg', function(image) {
      texture.image = image;
      texture.repeat.set(1,1);
      texture.needsUpdate = true;
  });
  
  // model
  var loader = new THREE.OBJLoader(manager);
  loader.load('models/obj/dla/dla.obj', function(object) {
  
    object.traverse(function(child) {
  
    if (child instanceof THREE.Mesh) {
  
      child.material.map = texture;
  
    }
  
  });
  </code></pre>
