Frogr is a desktop Flickr Organizer For Gnome. Or at least it will be.
Frogr only currently supports uploading of Photos to Flickr and the option to edit file details (titles, description, tags, etc) before uploading, but the developers have grand plans in their hands:
“At this moment Frogr is basically a flickr uploader for GNOME, but the plan is to iteratively evolve it towards a complete flickr manager which should allow things such as modifying properties for already uploaded pictures, managing flickr albums and so forth.”
Although the features are still coming along the current release is already a handy tool for bulk uploads to Flickr.
