Some useful image processing software:
Of course, Photoshop is a good one but it is not free. Some free ones exist out there. Here is a list which introduces some excellent free image processing software. GIMP, Paint.NET, Photobie, PhotoFiltre. This site contains more software.
With popularity of web 2.0 apps, many online image processing apps emerge. I list some ones I know:
