You will probably need to look at the source (or the docs for the Flickr api). I know the api uses Net::Http for communication which does allow for using proxies. Hopefully the flickr api gives you a way to set the proxy server and port.
If not you may have to modify the flickr module to do this where you see Net::HTTP.start:
proxy_addr = ‘your.proxy.host’
proxy_port = 8080
Net::HTTP::Proxy(proxy_addr, proxy_port).start(‘server.com’) {|http|
}
