I shoot 100% in RAW and use Nikon Capture NX for NEF raw file editing most of the time. Until recently, I have been uploading photos to Flickr by first saving the photo as JPEG to a folder, start Flickr Uploader, add the photos, then hit the upload button. I just found out that it could be much easier by cutting off the unnecessary steps.
First, download and install Flickr uploader here if you don’t have it already.
