The Swiss army knife of image editors

PhotoScape has to be the Swiss army knife of the photo processing world. This free program is becoming a favourite, and I can understand why. It packs in a surprising number of features, at least one of which is not even in PhotoShop (leastways, not the version of PhotoShop that I have). It gives you:
1. A fairly standard viewer (probably its weakest feature).
2. An Editor, where you can apply a multitude of adjustments and effects to your photos. There is everything from one click auto-levels and contrast to advanced color curves, complete with the ability to load and save presets. There are many color and tone adjustments and a number of filter effects from the practical (noise reduction) to fun (cartoon). You can also spruce up your photos with a variety of fun and funky frames. You can add text, shapes, etc. The editor also offers a flexible crop tool with a circular crop option.
3. Batch Editor, you can apply almost all the functions available in the editor to multiple files at once.
4. A multi-photo layout tool with over 100 choices of grid layouts to chose from. Simply drag and drop your photos into the boxes to create a quick collage.
6. AniGif: create a frame-based animation from multiple photos.
7. Splitter: cut your photo into multiple images based on a grid.
8. Screen Capture: take an image of your full desktop, a window, or a region of your screen.
9. Color Picker: sample colors from anywhere on your screen.
10. Raw Converter: simple converter for saving camera RAW files as JPEGs.
11. Rename: batch edit file names with custom text, date, time, serial numbers.
PhotoScape is free for non-commercial use and runs on Windows 98/Me/NT/2000/XP/Vista. The online help contains several videos to demonstrate the program features.
