If you are a flickr user, make sure you download the latest version (3.0) of the flickr uploader. It's an awesome tool that makes managing your flickr photos easy from your desktop and it works for both PCs and Macs. Using the new version of the flickr uploader, you can add titles and tags to photos, set privacy options or arrange your pictures in flickr sets -- all while being offline. When you get online, the upload manager manages the process of uploading all of your changes.
