FastStone Capture 5.3 The last free version available.
A screen capture utility with integrated image viewer and capture editor. Capture Windows, objects, selections or the entire desktop, and apply additional editing tools like resizing, sharpening, shapes, text, watermarks and more. You can send the capture to the image viewer, clipboard, or directly to a file. Other features include support for image viewing, a screen magnifier, a color picker and support for capturing of scrolling windows (ex: entire web page). Supports all major graphic formats including BMP, JPG, JPEG 2000, GIF, PNG, PCX, TIFF, WMF, ICO and TGA.
FastStone is a great screen capture utility having a few features that others lack. But FastStone Capture became commercial with a shareware (30 day trial) starting with version 5.4.
You can download the "free for home use" version here. (right-click "Save Target As...)
Or the shareware verions from the publishers site below. The free version offers most everything the newer versions do.
