  • Hello @cuartostudio

    Ideally, you should use srcset for this (explained here). But if this isn’t an option, you can also use a bit of Javascript for this:

    Your HTML could look something like this:

    <img src="<?php echo get_field('image'); ?>" data-small-src="<?php echo get_field('image_small'); ?>" />

    Then the Javascript (jQuery):

    var windowWidth = $(window).width();
    if (windowWidth <= 768) {
      $('img[data-small-src]').each(function() {
        var small_src = $(this).data('small-src');
        $(this).attr('src', small_src);

    What that basically says, is if the window width is less than 768 (or whatever width you want this to happen), then find all the <img> tags with the data-small-src data attribute, loop through them and update its src value, with the ‘small-src’ value which will be the URL of the smaller image.

    You could optionally put that function into a $(window).resize event too so that it swaps out the images based on image size, but then you’ll need to add an else to that if statement so that it reverts back to the large size if necessary.

    Hope that helps?
