随着使用的深入，发现soul模板存在一个我不是很喜欢的东西??在显示评论人头像的时候，会调用

<img src=" <?php echo TEMPLATE_URL; ?> <?php $b=array( "images/logcmt/a.png"=>"a", "images/logcmt/b.png"=>"b", "images/logcmt/c.png"=>"c", "images/logcmt/d.png"=>"d", "images/logcmt/e.png"=>"e", "images/logcmt/f.png"=>"f", "images/logcmt/g.png"=>"g", "images/logcmt/h.png"=>"h", "images/logcmt/i.png"=>"i", "images/logcmt/j.png"=>"j", "images/logcmt/k.png"=>"k", "images/logcmt/l.png"=>"l", "images/logcmt/m.png"=>"m", "images/logcmt/n.png"=>"n"); ?> <?php echo array_rand($b); ?>"  />

但是我想为什么不调用Gravatar呢，自己动手丰衣足食，只需要把上边那么长的代码改成这么一句就好了：

<img src="<?php echo getGravatar($comment[’mail’]); ?>" />

哇咔咔。问题解决
