Random section background image on each visit/refresh

Recommended Posts

Hi all,

I'm trying to get the background image of a section (first section on a 7.1 home page) to randomly load a different image each time the user visits or refreshes the page - probably around 8 images in total.

I found the below code on an older post - sometimes it works, sometimes a new image loads but the original suddenly pops up over top of it.

Any suggestions that might iron out the bugs here would be appreciated.

<script>
document.addEventListener('DOMContentLoaded', function() {
  var images = [
    'https://randomwordgenerator.com/img/picture-generator/54e9d1454b5ba914f1dc8460962e33791c3ad6e04e507440752b7edc9649c2_640.jpg',
    'https://randomwordgenerator.com/img/picture-generator/50e2dc464e4faa0df7c5d57bc32f3e7b1d3ac3e45658724e77267bd493_640.jpg',
    'https://randomwordgenerator.com/img/picture-generator/50e2dc464e4faa0df7c5d57bc32f3e7b1d3ac3e45658724e77267bd493_640.jpg',
    'https://randomwordgenerator.com/img/picture-generator/nick-dunlap-h65WkTvyWJY-unsplash.jpg'
].sort( () => .5 - Math.random() );
    var randImage = images[0];
    document.querySelector(".homepage article.sections section:first-child .section-background img").src = randImage;
    document.querySelector(".homepage article.sections section:first-child .section-background img").setAttribute("srcset", "");
});

</script>

Hi,

We can achieve this with Gallery. Do you still need help on this?

Hi tuanphan,

Yes still looking for a suitable solution here.

Ideally I was hoping to achieve this using background images as I have a bit of content to go over top of the imagery. A gallery may be a workable option though if I cant get background images to work - how do you go about achieving random load of gallery images? (I don't want users to be able to scroll through other images either).

Thanks,
Aaron
