Flickr is one of the most popular photo hosting services on the Internet with thousands of photos uploaded every minute. Some companies, organizations and networks have decided to block Flickr due to its popularity to prevent their employees from accessing Flickr in those networks during work time. There are basically two options to access Flickr if it has been blocked in the computer network or on the local computer system. The first option are proxy servers, the second an alternate url. Proxy servers are used by millions of users a day to access websites that have been blocked in their computer networks. They are especially popular to access blocked social networking sites like Facebook or MySpace but also other popular websites like Youtube or Flickr. Proxies tend to get banned fast by network administrators who basically need to check the traffic logs to find and ban the proxy servers used by company employees. More interesting than using proxy servers – which can also pose a security risk if the user wants to log into Flickr – is the use of an alternate url that provides full Flickr functionality. All that needs to be done is to replace www.flickr.com with www.flickr.mud.yahoo.com .
