Photoshop Express

This Flash-based app has 17 basic buttons for editing, a thumbnail display of all the different changes you've made, import (from Picasa and Facebook, among others) and 2 GB of album storing space.

No layers here, no fancy pants masking. But for 95% of your photos, it offers pretty much all you need to fix ‘em up, and it does it with style. Whether adjusting exposure, white balance, or hue, touching up blemishes, or distorting your image, Photoshop Express provides an easy slider and thumbnails to give you an instant preview of your image at various settings. Even undo is better than you’d expect.
