Kflickr

I singned up for a Flickr account a few weeks ago. It's a very nice thing but Uploading pictures to Flickr via its Web-based interface is a hassle, particularly if you have dozens of shots to upload. Linux users have a better choice, though, in the form of Kflickr, a simple application for uploading shots to Flickr that will have your family photos online in no time....

Here is a very nice article I found on Linux.com concerning Kflickr.
