The developer (Steven Vondruska) of FlickrImportr cannot dedicate the time required to continue development and support of this application. It was no easy decision but as of 15 May 2012, the application was taken offline.
Steven never thought this application would get as much use as it has. It has posed many systems administration and devlopment challenges to him. He is sad to pull the plug on the project, but hopes open sourcing the project will inspire other people to help solve what seem like simple problems.
The application source was released under the GPL license at http://flickrimportr.info/source/.
