Sumo Paint is a 'free' online image editing application.
High-end image editor SUMO Paint is a fairly impressive clone of Photoshop's major features inside a browser window. Sumo Paint is designed more for image creation rather than image editing.
If you're without your favorite desktop editor and in need of photo-tweaking power, SUMO can load images from uploads, URLs, and do its own in-browser copy and paste. SUMO Paint is free to use.
