I've recently discovered this awesome proyect:

https://art42.net/ #

I liked so much that I integrated into this blog.

Deterministic (random) image #

The url of the images are like this:

https://cdn.vcloud42.com/file/art42-cdn/cubism/seed_seed_0000089306.jpg

so obtaining an image is a matter of providing a number.

Because I want to use the same image for the same tag, first I create a random number by hashing a string:

function hashStringToInt(str, max = 293916) {
  var hash = 0;
  for (var i = 0; i < str.length; i++) {
    hash = (hash << 5) - hash + str.charCodeAt(i);
    hash = hash & hash;
  }
  return Math.round((max * Math.abs(hash)) / 2147483648) + 7;
}

And then create a url:

export function imageUrl(text: string) {
  const id = hashStringToInt(text).toString().padStart(10, "0");
  return `https://cdn.vcloud42.com/file/art42-cdn/cubism/seed_${id}.jpg`;
}
