GFW stands for ‘Great Fire Wall’. It is used for blocking some websites (like flickr.com) from China mainland. So people in China cannot see any pictures of flickr. This plugin will grab the pictures from flickr image library by your web server. So you need a web server that located in which flickr isn’t blocked, for example, US.
Requirements
- A web server that can visit flickr’s libraries directly
- ‘allow_url_fopen’ of php.ini should be “1”.
