<tr>
<td><span class="style5">Usuario</span> </td>
<td><input name="nombre" type="text" id="nombre3" size="10" tabindex="1"></td>
<td width="46%" rowspan="2" align="right" valign="middle"><div align="left">
<input name="imageField2" type="image" src="images/login.gif" width="32" height="32" border="0" tabindex="3">
</div></td>
</tr>
<tr>
<td width="19%"><span class="style5">Contraseña</span> </td>
