AVI Editing tools

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, and resize images, adjust colors, and create collages. It 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, including a red-eye removal tool that has seen dramatic improvements. Unlike most free image editors, Paint.NET supports layers, history, and has an actions manager. The pleasing interface boasts semitransparent windows for ease of use.

FastStone:
FastStone Image Viewer for Windows can batch-convert files into a number of popular image formats including GIF, BMP, PSD, and PNG, and the slide-show creator allows you to apply transitions, specify the interval between images, and add your own MP3s as a soundtrack. Cnet’s editor recommends this program to everyone but professional designers.

GIMP:
One of the most powerful general-purpose image editors around, the upgrades make the GNU Image Manipulation Program eminently comparable to Photoshop. Older features include channels, layers and masks, filters and effects, tabbed palettes, editable text tools, perspective clone, improved printing, and color operations such as levels. New improvements include GEGL integration for 32-bit color support, dynamic brushes, and more options for the free select tool. It even has regex-based pattern matching for power users.

IrfanView:
The program lets you open and edit images, as well as multiple media formats. You can cut and crop images, apply batch conversions, add, sharpen, or blur effects, create panoramas, and change color modes easily. The program continues to add support for an array of file formats and has plug-in support for most image, video, and sound formats, including MP3, AVI, audio CD, and WMA. The interface is far from fancy but should be easy enough for most users to figure out. An IrfanView Thumbnails shortcut on the desktop offers an Explorer-like file tree that quickly displays all images in a particular folder.

PhotoScape:
Add another name to the roster of feature-rich freeware image editors: PhotoScape. Although it eats and leaks about as much memory as Firefox, this editor is perfect for those making the jump between JPEG and am-pro dSLR work.
It supports RAW, as well as all other major image formats from JPEG and PNG to animated GIFs. It comes with prebuilt templates for users to create photo collages, fumetti, and Web comics, and has a standard set of red-eye removal, light/shadow, and contrast-editing features.
