       var year=(((new Date().getFullYear())%100<10) ? "0":"") +(new Date().getFullYear())%100;
       var fecha=mes.concat("/".concat(dia.concat("/".concat(year))));
       if((paramJS==fecha)){
           result = "OK";
       }else{
           result = "Mal, la fecha no es la de hoy";

      result = "OK";
      for (var i = 0; i < window.document.images.length; i++) {
           if (!(window.document.images[i].complete)) {
              result = "ERROR, image with src:"+window.document.images[i].src+" not found";
           }
   
           if (typeof window.document.images[i].naturalWidth != "undefined" && window.document.images[i].naturalWidth == 0) {
              result = "ERROR, image with src:"+window.document.images[i].src+" not found";
           }
