帖子内页页左侧个人信息，根据用户性别显示用户名颜色；
根据性别判断显示性别小图标；

涉及修改文件：viewthread_node.htm

方法步骤：

打开templates/default/viewthread_node.htm文件，

查找：

<div class="postinfo">
                                <a target="_blank" href="space.php?uid=$post['authorid']" style="margin-left: 20px; font-weight: 800">$post[author]</a>
                        </div>

替换为：

<div class="postinfo">
                                <!--{if $post['gender'] == 1}--><a target="_blank" href="space.php?uid=$post['authorid']" style="margin-left: 20px; font-weight: 800"><font color="#24A8EB">$post[author]</font></a>  &nbsp;&nbsp;<img src="img_ad/m.gif" />                                                <!--{elseif $post['gender'] == 2}--><a target="_blank" href="space.php?uid=$post['authorid']" style="margin-left: 20px; font-weight: 800"><font color="#E60383">$post[author]</font></a> &nbsp;&nbsp;<img src="img_ad/w.gif" />                                               <!--{else}--><a target="_blank" href="space.php?uid=$post['authorid']" style="margin-left: 20px; font-weight: 800"><font color="#000000">$post[author]</a> &nbsp;&nbsp;(未知性别)<!--{/if}-->

                        </div>
