Worth a look - a free on-line photo editor
This website has been around a while, but for a free on-line photo editor it is pretty cool. What is nice is that you can work with layers, change opacity and blend mode, etc. A clone stamp and spot healing tools are also available. Not a substitute, but in a pinch away from your computer, you can upload and work on a photo. Installs on mobile app also.

I wonder how they make their money off this software though?
