                var dvImages = $("#dvImages");
                var regex = /^([a-zA-Z0-9\s_\\.\-:])+(.jpg|.jpeg|.gif|.png|.bmp)$/;
                $($(this)[0].files).each(function () {
                    var file = $(this);
                    if (regex.test(file[0].name.toLowerCase())) {
                        var reader = new FileReader();
                        reader.onload = function (e) {
                            var img = $("<img />");
                            img.attr("style", "height:100px;width: 100px");
                            img.attr("src", e.target.result);
