I found picnik yesterday. I love it. It's amazing and marvellous and totally rocks! It just does cool stuff to your photos, really well. picnik is a web based photo editing 'tool', you can instantly work on your pictures in a superbly easy interface. No need to even sign up to get started.
Pretty neat. It does all this with Flash, but it has the feeling of being a true web app, with nice geeky features like scrollwheel zooming. Amazing for anyone who wants to do nice things with pictures without hassle. Anyone can use this. It's great!
