If all you want is a quick image retouch, Photoshop is overkill. Paint.NET, on the other hand, is an open-source freeware editor with all the essentials, including tools to crop, rotate, resize images, adjust colors, and create collages.

Paint.NET supports common image formats--JPEG, PNG, GIF, TIFF, and others--but not high-resolution RAW files. There are enough basic and intermediate effects and features to keep image-tweakers happy, though the red-eye removal tool is notably weak; those images may require manual attention.

Unlike most free image editors, Paint.NET supports layers and has an actions manager.(This is good for graphic lovers)

A powerful yet simple image and photo editor tool. It has been compared to other digital photo editing software packages such as Adobe® Photoshop®, Corel® Paint Shop Pro®, Microsoft Photo Editor, and The GIMP.
