Export iPhotos to Flickr
If you're an iPhoto user, there's a new plugin that will make your uploads to Flickr much easier. FFXporter allows you to quickly and easily export your photos to Flickr - one at a time or in bunches - while preserving geo tags, descriptions, titles, keywords and ratings. There are more sophisticated programs to do this, but FFXporter is free. So far there are more than 12,000 users of the service.
