Free Windows tool No. 9: Paint.Net
With dozens of good free image editors around, it’s hard to pick one. Irfanview has tremendous viewing, organizing, and resizing capabilities. GIMP ships with powerful tools and an enormous array of add-ins. Faststone Image Viewer lets you edit full-screen, and has a screen-capture capability. And that doesn’t even brush the surface of the Picasa vs. Windows Live Photo Gallery maelstrom – a religious debate worthy of volumes. For powerful, easy-to-use photo editing, with layers, plug-ins, and all sorts of special effects, along with a compact, easily understood interface, I’ll stick with Paint.Net. Although it requires the .Net Framework, the program puts all the editing tools a non-professional might expect into an intuitive package..
