The GIMP is the GNU Image Manipulation Program. it is a featureful graphics editor, which is often called "The Photoshop of Linux". Despite its reputation in the GNU/Linux world, it is cross-platform, and works well on Windows too. It is mainly intended for photo editing, but is also good for pixel art.

Update: As of 2.3.9+, Gimp has become a lot better for pixelling. With

• The ability to easily select palette colors from the keyboard (move to next/prev palette color)
• The 'clipboard' brush and pattern, which reflect the current contents of the clipboard, make it easy to cut out parts of the picture and paint with them. This is particularly helpful for tile and background creation.
• The 'Colormap arrange' plugin can help you to arrange the 16 color palettes of any sprites you want to import. It preserves the appearance of the image regardless of how you rearrange the colors, so it's very easy to use.

If you feel up to using a development (ie. maybe not as stable) version, you can get 2.3.x versions from [1] (Not the link given below)
