代码基本原理，新建一个自定义分类法“shot”，自动从另一个站点的RSS抓取文章，放在一个数组中，再用这个数组创建“shot”文章，并为文章添加自定义栏目image和link_url，方便调用缩略图和原文链接。
将下面代码添加到当前主题functions.php中即可。
- <?
- add_action( \’init\’, \’register_cpt_shot\’ );
- register_cpt_shot() {

修改第66行的”http://dribbble.com/tammyhart/shots.rss“为准备抓取文章站点的RSS地址，还可以修改第80行后的”shot“为你所用主题自定义分类法名称，抓取的文章会自动添加到该分类法中。
上述代码中并没有抓取文章内容的功能，仅供参考学习之用。
