S is for SUMO Paint!
Sumo Paint
This is further to my earlier post on image editors like Picasa, Photoscape, etc.
Sumo Paint is both an image editor as well as a creator. The interface is very similar to Adobe Photoshop but it has much lesser functions (what do you expect? its free!).
All editing is done online via its website. However, you can upload image files from your own computer to edit on the website.
Its easy to use and helps if you have a fast internet connection.
