<h2>设置微信打赏二维码</h2>
<p>
请先通过手机微信获取付款二维码，操作步骤：
</p>
<p>
1.打开微信，点击右上角“+”号，点击“收钱”，即可进入微信收钱页面<br>
2.长按二维码，点击“保存图片”，即可保存图片到手机<br>
3.将图片上传到电脑，可以通过微信传输助手传到电脑，或者其他方式将图片传到电脑<br>
4.将二维码图片传到WordPress站点，在WordPress后台“多媒体”-"添加"，上传二维码，<span style="color: red; ">然后复制上传到服务器的二维码图片的url</span><br>
提示：建议把微信生成的二维码图片先进行裁剪再上传。有任何疑问请发邮件到tanteng@gmail.com，将第一时间回复，谢谢！
