“FlickrSave is a GIMP plugin which adds an option to directly
upload a picture to Flickr. It uses Christophe Beauregard’s
flickr_upload tool as a backend. The plugin supports setting title,
description, tags and privacy, and works in both GIMP-2.2 and
GIMP-2.4RC under Linux…“In all honesty, this is more of a ugly hack than a full-fledged
plugin, but it works OK. And maybe it will inspire somebody to
write a better plugin. In the meantime, please use and enjoy
it…!”
