推荐一个十分好用的wordpress插件：OnePress Image Elevator 我以前自不量力也实现过一个蹩脚的相关插件，害人害己，现在已经删除了，还是先学习学习别人的源码。
Image Elevator allows you to paste images into your posts directly from clipboard! In other words, you can paste images directly from your favorite graphical editors or from any screen capture programs. Just copy & paste.Views 2033
