如何增加微信分享链接的小图片

注意注意注意,重要的事情说三遍,下面的两种方法都不好使了 这是2015年的方法,最新方法点此查看http://www.sky00.com/archives/1460.html
下面说两种方法,一种HTML的,一种JS的!
1、微信分享链接的小图片很多游戏之类是用JS写的,如果懒得用JS函数就这样写,在<head>与</head>之间加上下面的代码就好了,注意这个图片必须是300px*300px的!

1
<div id="wx_pic" style="margin: 0 auto; display: none;"><img src="images/share.jpg" /></div>

2、如果想写的详细一点。比如描述了跳转后的链接要改变之类的就复制下面的JS放到网页里,修改JS开始的变量即可!
