The Flickr desktop uploader sits on your desktop for heftier uploading needs or offline photo management. Drag and drop single photos or videos, or select a whole folder. Even reorder how photos will be displayed in your photostream.
Version 3.2.1: Released June 11, 2009. This release is available in 8 languages.
The most recent flickr Uploader Desktop client is super powerful! It's definitely worth the download, and it's much easier to upload lots of photos with the new drag-n-drop functionality. I strongly recommend giving it a try if you're a flickr user. Flickr just keeps getting better and better...
