  <span class="font"><font color="#FF0000">注意：请不要用此功能上传大于2M的文件。
  1M等于1024K，1K等于1024个字节<br>
</font></span></div>
<form method="post" action="sub_upload.asp" enctype="multipart/form-data">
  <table border=0 cellspacing=0 cellpadding=0 align=center width="333">
    <tr>
<td height=20 width=60>&nbsp;文件</TD>
<td height="16" width="371">
<input type="file" name="src" size="20" value="浏览">
