Run something after images from ajax are loaded.

ajaxImagesLoaded.js

$(document).ready(function() {
    // Check for all images to be loaded
    $.fn.imagesLoaded = function() {
        var dfds = [];
        var $imgs = this.find('img[src!=""]');

        $imgs.each(function() {
            var dfd = $.Deferred();
            dfds.push(dfd);
            var img = new Image();
            img.onload = function() {
                dfd.resolve();
            }
            img.src = this.src;
        });

        return $.when.apply($,dfds);
    }
});

// Use case
function someFunction(variable){
    $.ajax({
        cache: false,
        dataType : 'json',
        url: wp_info.home_url + '/wp-admin/admin-ajax.php',
        type: 'POST',
        data: {
            action: 'function_in_functions_php',
            variable: variable
        },
        error: function(response, textStatus, errorThrown) {
            console.log(response.error);
        },
        success: function(response, textStatus, jqXHR) {
            if (response.status == 'success') {
                $('.div').html(response.html).imagesLoaded().then(function() {
                    somethingHere();
                });
            }
        }
