When Flickr have got the great idea to let 1Tb of free space to upload photos to the native resolution I think to upload all my photos, also only as backup (the photos can be private) I've decided to do my own uploader.
Simply I've got all my photos into folders, and the name of the folder is the date and the description of the event.
with gFlickrUploader you choose the parent folder of the folder events.
The program loads the photos and the videos creating the set with the folder name (if doesn't exists)!
This page appears the first time and let you to aythenticate to flickr, pess the button Authenticate and your browser will be launched navigating to the pag that authorize gFlicrkUploader to connect with your acaccount, confirming the webpage shows you a code, copy and paste into the step2 field and press Complete and a message with the authorization satus will be shown.

you have the possibility to choose the privacy level of your photos: public, family and friends or private.
