I was searching around for a software to do image editing and stumble upon this really cool and easy to use software called Paint.Net… Give it a try and you will surely say good bye to Microsoft Paint 😛
Paint.NET is free image editing and photo manipulation software designed to be used on computers that run Windows. It supports layers, unlimited undo, special effects, and a wide variety of useful and powerful tools.
It started development as an undergraduate college senior design project mentored by Microsoft, and is currently being maintained by some of the alumni that originally worked on it. Originally intended as a free replacement for the MS Paint software that comes with Windows, it has grown into a powerful yet simple tool for photo and image editing.
The programming language used to create Paint.NET is C#, with a small amount of C++ for installation and shell-integration related functionality.
If you do not have the .NET Framework installed, or if you are not sure, feel free to download Paint.NET v3.0 with .NET Framework 2.0 (50 MB).
