``javascript
// Convert images into pngsmith objects
var images = ['img1.jpg', 'img2.png'];
pngsmith.createImages(this.images, function handleImages (err, imgs) {
// Create a canvas to draw onto (200 pixels wide, 300 pixels tall)
pngsmith.createCanvas(200, 200, function (err, canvas) {
// Add each image at a specific location (upper left corner = {x, y})
var coordinatesArr = [{x: 0, y: 0}, {x: 50, y: 50}];
imgs.forEach(function (img, i) {
var coordinates = coordinatesArr[i];
canvas.addImage(img, coordinates.x, coordinates.y);
}, canvas);

// Export canvas to image
canvas'export' {
result; // Binary string representing a PNG image of the canvas
});
});
});
