Random Images from same url-CodePudding

I was given a prompt to loop through items in a javascript object. Each item has an imageUrl property that points to this url: https://www.placebeard.it/400x400 This url is supposed to generate random images on each visit, but when I loop over the objects I end up getting the same image 25 times. When I inspect the page and click on the images I get random images. This is a codepen project, could that be the problem?

Here is a sample of the code used to get the image

const makeCard = (item) => {
  let card = document.createElement('div');
  card.classList.add('card', 'p-0');

  // card image
  let image = document.createElement('img');
  image.classList.add('card-img-top');
  image.src = `${item.imageUrl}`;
  console.log(image.src);
  card.appendChild(image);

  //... append to container
}

Thanks

This is a trick that your browser plays: because you point the image to the same URL, the browser will think it's the same image. You can get in front of it by adding a dummy query string and a random value, e.g.:

const makeCard = (item) => {
  let card = document.createElement('div');
  card.classList.add('card', 'p-0');

  // card image
  let image = document.createElement('img');
  image.classList.add('card-img-top');
  image.src = `${item.imageUrl}?random=${Math.random()}`; // notice this
  console.log(image.src);
  card.appendChild(image);

  //... append to container
}

And you should get different images (servers usually ignore query strings they don't recognize).

You Can Add Images src in json file and transform the json file to the javascript object and make a loop with images count
