I normally use the command-line Flickr uploader. Just hacked this up for GUI-inclined folks. Also, I’m not much of a desktop guy—the web is the desktop—so, yeah, just playing around. The code is here. Requires the Ruby API and Ruby-GTK. (The Ruby bindings for GTK are nice to work with, by the way.)
Doesn’t look very good, etc. I’ll probably try to improve on it.
While looking for pictures to test with, I found a picture of one of my college friends—she with the ocean behind her. There’s something about that picture that makes me smile. That’s my wallpaper for now.
