Is it possible to preload textures and images in ThreeJS?

Question

Is it possible to preload textures and images in ThreeJS?

Is there a straightforward way to preload Textures and Images in ThreeJs? I currently load them all into an array using the following method:

myTextureArray.push(new THREE.ImageUtils.loadTexture('../textures/floor_red.jpg');

How can I determine if and when all Textures have been successfully loaded?

If you're curious, here is an older version link for reference:

If you're working with Three.js, there's a handy Loading Manager available that helps you keep tabs on all your loaded Textures and Objects.

Here's a quick example of how you can implement it:

var textureManager = new THREE.LoadingManager();
textureManager.onProgress = function ( item, loaded, total ) {
    // This function is triggered after each item is loaded
};

textureManager.onLoad = function () {
    // All textures have been loaded
    // Do something...
};

var textureLoader = new THREE.ImageLoader( textureManager );
var myTextureArray = [];
var myTexture = new THREE.Texture();
myTextureArray.push( myTexture );

textureLoader.load( 'my/texture.jpg', function ( image ) {
    myTexture.image = image;
} );

This code was tested in Three.js version r71.
