What is the best way to import a local image into THREE.js?

Question

What is the best way to import a local image into THREE.js?

I'm struggling to apply an image onto an object using the following code:

var texture = new THREE.TextureLoader().load( 'crate.gif' );
var geometry = new THREE.BoxBufferGeometry( 200, 200, 200 );
var material = new THREE.MeshBasicMaterial( { map: texture } );
mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );

Even though I have "crate.gif" in my local folder, it doesn't display on the box.

The developer mentioned that local image loading won't work and suggested using a web server or data URL as a solution.

However, setting up a web server is not an option for me.
I might consider converting images to Base64, but I don't know how to implement this.

I suspect the image isn't showing because it hasn't finished loading. What's the simplest way to load an image?

Replacing an image filename with a Data URI can be just as simple, when executed correctly:

let shape = new THREE.BoxGeometry(1, 1, 1);
let texture = new THREE.TextureLoader().load( "data:image/png;base64,/9j/4ABESkgHWE--(truncated-for-security)--BCdFQDIBQQAAEgAAMABAAD" );
let material = new THREE.MeshBasicMaterial( { map: texture } );
let cube = new THREE.Mesh(shape, material);
scene.add(cube);

If you want to use an image as a texture, one method is to require it and specify the relative path of your image:

This technique has been tested with React and it functions properly for me.

const textureImage = require('../assets/images/image.png');
const texture = new THREE.TextureLoader().load(textureImage);
const geometry = new THREE.BoxBufferGeometry( 200, 200, 200 );
const material = new THREE.MeshBasicMaterial( { map: texture } );
const mesh = new THREE.Mesh(geometry, material);
scene.add(mesh);
