I absolutely love Photoshop. It’s by far the best image editor out there but unfortunately you have to pay a premium for it. For those of you who are looking for a cheap alternative to Photoshop, look no further. I have gathered what I think are some great alternatives that will meet most if not all of your photo editing needs and at a great price…FREE.
GIMP stands for GNU Image Manipulation Program. It’s probably the most robust of the free alternatives listed here. It has support for GNU/Linux (i386, PPC), Microsoft Windows (XP, Vista), Mac OS X, Sun OpenSolaris and FreeBSD.
Paint.NET is free a image and photo editing package that runs on Windows only.
Krita, while not as robust as GIMP or Paint.net, is still a very powerful alternative to Photoshop.
Seashore is more limited than the previous picks however it does a solid job with basic image editing. It only has supprt for Mac OS X
Cinepaint is unique that it is used by major studios for editing feature films. It is also a great image editor. No Windows version available.
PhotoFiltre is a small basic image editor
Active Pixels has a lot of the same menus and keyboard shortcuts that Photoshop has. In my opinion it is one of the standouts of this list.
The next four are full featured online editors.
