Free imaging software for windows

Adds image processing capabilities to your Python interpreter The Python Imaging Library supports many file formats, and will provide you with powerful graphics capabilities and image processing.
This library provides extensive file format support, an efficient internal representation, and fairly powerful image processing capabilities.
The core image library is designed for fast access to data stored in a few basic pixel formats. It should provide a solid foundation for a general image processing tool.
Image Archives
The Python Imaging Library is ideal for for image archival and batch processing applications. You can use the library to create thumbnails, convert between file formats, print images, etc.
The current version identifies and reads a large number of formats. Write support is intentionally restricted to the most commonly used interchange and presentation formats.
Image Display
The current release includes Tk PhotoImage and BitmapImage interfaces, as well as a Windows DIB interface that can be used with PythonWin and other Windows-based toolkits. Many other GUI toolkits come with some kind of PIL support.
For debugging, theres also a show method which saves an image to disk, and calls an external display utility.
Image Processing
The library contains basic image processing functionality, including point operations, filtering with a set of built-in convolution kernels, and colour space conversions.
The library also supports image resizing, rotation and arbitrary affine transforms.
Theres a histogram method allowing you to pull some statistics out of an image. This can be used for automatic contrast enhancement, and for global statistical analysis.
System requirements:
- Python 2.2 or above

Image Dif is a C++ application which will display the differences between two pictures.
Image Dif calculates those differences at pixel level or region level.

The application offers image manipulation for single images and for complete folders of images. This is an extremely simple, and possibly useful tool that is intended to be used as a learning aid for people new to C# and the .NET Framework 2.0.
The application offers image manipulation for single images and for complete folders of images.
Images is also very small and easy-to-use, supporting four important pictures formats: JPEG, BMP, GIF and PNG.

Image Counter is a Firefox extension that will display a count of total images of a web page and his frames in status bar
