Flickr Set Manager
Note: This is a public beta of the new Flickr Set Manager and includes many new features, including date and location-based sets. Remember, this is beta software and not a formal release, so some things still might not work perfectly and are likely to change. If you do come across any problems, please report them in the Set Manager group on Flickr. If you prefer, you can continue to use the old set manager here.
Flickr Set Manager allows you to automatically create new sets on Flickr based on various criteria such as interestingness, date posted and tags, or even from a random set of photographs.
Click on the link below to start. Before you can start using it for the first time, you will be taken to the Flickr web site and asked to grant permission for write access - this is so that Set Manager can create new sets in your Flickr account and add photos to them. Don't worry, you can alway revoke this permission at any time by going here.
If you have any questions or comments about the Set Manager, please join the Flickr Set Manager group.
