I just realized I've never posted this before, but it's so useful. ImageShack is a site where you can upload a picture and have it hosted on their site for free. No hassle, totally free, no sign-ups needed. I've no idea how they make their money (they run some ads, but I guess I'm pretty blind to them) but I've used it several times before to share incidental images, so if you want to get a photo up somewhere quick without resorting to FTP or your blog software.. check it out.
