Allows you to edit photos online using layers. It is still in Beta, but looks promising as an alternative to Photoshop.
From the website –
“Fauxto, as far as we know, is the only full-featured image editor on the web. Our goal is free-range editing capability and a YouTube like usage model. You can edit, save to the server and distribute anywhere. Though it is most certainly in a beta stage of development, and we are still working out kinks and tweaking the system as a whole, we think you’ll be happy with what you find.”
