How to modify this check for many pictures, and not for one?

Question

JavaScript

There is a code that checks for the presence of a picture (one). And how to remake to check a lot of pictures?

var img = new Image();
img.src = 'https://upload.wikimedia.org/wikipedia/commons/thumb/8/8b/Proton-K-Zarya.jpg/800px-Proton-K-Zarya.jpg';
img.onload = function(){alert('картинка существует')};
img.onerror = function(){alert('картинка не существует')};
