"You used to have to pay a professional-level price if you wanted a professional-level image-editing program. I'm not talking about simple editors that let you open and save in different formats or image managers that let you make slide shows [okay this means me].
I'm talking about the pro applications that let you get down and dirty with your images. The kind of programs that let you use filters and effects, edit the smallest of details, and separate your projects into manageable layers.
Most people think Photoshop [Hey Shaun!!] is the only program available that gives you comprehensive control over images and that it's going to cost you if you're serious about image editing. They would be wrong.
The GIMP [(GNU Image Manipulation Program] is an open-source image-editing app that offers all of the functions of more well-known (and expensive) programs for free. If editing images is your profession or you would like to see the laundry list of cool functions for The GIMP, check this app out.

The volunteer developers of The GIMP have been working hard to develop a polished, user-friendly, and freely distributed image editor. This application caught our attention--and hearts--as one of the most powerful general-purpose image editors around.
The application's features include channels; layers and masks; filters and effects; tabbed palettes; editable text tools; and color operations such as levels. The application provides professional tools that can stand against the big boys without the hefty price tag.
The only downside to this otherwise flawless program is the installation process. As it stands now, you have to install Apple's X11 app and The GIMP separately. Once installed, though, the program is extremely powerful and easy to work with. The GIMP is ideal for amateur photographers, Web designers, and anyone who wants to create and edit professional-quality digital images on a budget.
