    function createForm(textN, number) {
      data = "";
      inter = "'";
      if (number < 11 && number > -1) {
        for (i = 1; i <= number; i++) {
          if (i < 10) spaces = " ";
          else spaces = " ";
          data = data + " <input name=" + textN + i + " type=text value='' size='30' maxlength='100'>"

        }
        if (document.layers) {
          document.layers.cust.document.write(data);
          document.layers.cust.document.close();
        }
        else {
          if (document.all) {
            cust.innerHTML = data;
          }
        }
      }
      else {
        window.alert("请不要超过10张图片.");
      }
    }
</script>
</head>
<body>
  <form name="prodtable" action="">
  <input type="radio" name="more_pic" checked value="0" onclick="JM_wu(s1)">无
  <input type="radio" name="more_pic" value="1" onclick="JM_you(s1)">有 <span id="s1" style="display:none">
    <input name="more" type="text" value='1' size='5' maxlength='2'>
    <input type="button" value="张大图" onclick="createForm('more',document.prodtable.more.value);">
    <span id="cust" style="position: relative;"></span></span>
  </form>
</body>
</html>

这只是一个指引的小例子，同学们可以把按钮换成浏览图片按钮。
