Feel free to take any of these icons - with credit to baratron, please. Outside livejournal, credit them to helen-louise (http://baratron.livejournal.com). Thanks!
Right-click on the icon you want, hit "Save image..." and type in a filename. They're all jpegs. Note that by default, they'll all save as t6464.jpeg - so you'd better pick a filename if you want more than one!
