flickr重定向到大图的问题
用Redirector.uc.js的重定向，规则如下
{
//http://bbs.kafan.cn/thread-1801036-1-1.html
name: "flickr >> 原始大图",
from: /^(https?:\/\/c\d\.staticflickr\.com\/\d\/\d+\/\d+_[^\._]+)(_[a-z])?(\.jpg)$/,
exclude: /^(https?:\/\/c\d\.staticflickr\.com\/\d\/\d+\/\d+_\w+)_b(\.jpg)$/,
to: "$1_b$3",
regex: true
}浏览flickr出现无法显示图片，点击放大又可以显示，比如浏览下面网页
https://www.flickr.com/photos/mytripsmypics/albums/72157604812751507/with/2485664017/ 出现下面无法显示封面 
求修改 |
