Tired of the limitations using MS Paint that comes with your computer? Try Paint.NET for an intuitive, user-friendly (and free!) alternative.
Transparent backgrounds, layers, and special effects in this application make it a useful tool for the novice, or the expert, image editor.
Paint.net offers tutorials for beginners as well as tutorials on text effects, distortions, textures, and more.
Caution, however: the download comes with some partner applications that will install with Paint.NET – You may want to run through the install, then uninstall unwanted applications through Add/Remove Programs in the Control Panel. Some are plugins – disable these through your browser.
