jQuery(document).ready(function($) {
    WfMediabox.Plugin.add('image', function () {
        this.type = "image";

        // create image html (leave src blank)
        this.html = function (data) {
            
            // add time to the url to prevent caching...
            data.src += '?' + new Date().getTime();
            
            var $img = $('<img src="https://www.joomlacontenteditor.net/' + data.src + '" class="wf-mediabox-img" alt="' + decodeURIComponent(data.alt || data.title || "") + '" tabindex="0" />');

            if (data.params) {
                $.each(data.params, function (name, value) {
                    $img.attr(name, value);
                });
            }

            return $img;
        };

        this.is = function (data) {
            var src = data.src;
            // remove query to test extension
            src = src.split('?')[0];
            return /image\/?/.test(data.type) || /\.(jpg|jpeg|png|gif|bmp|tif|webp)$/i.test(src);
        };
    });
});

Is there any other possible solution - without using this script? Causes trouble.

jQuery(document).ready(function($) {
    $('.jcepopup').attr('href', function(i, val) {
    	if (/\.(jpeg|jpg|png)$/.test(val)) {
    		return val += '?' + new Date().getTime();
    	}
    });
});
