Free is great, isn't it? I really like free software. HyperSnap DX might be the best screen capture tool I have found on Windows, but this one is free.
HoverSnap is a small but powerful screen capture utility that can capture the entire desktop, the active window or custom areas on the screen and save the image to JPEG, GIF, BMP or PNG format. It can even automatically rename and resize the screenshot and save it to a folder of your choice. Additional features include integrated FTP upload and support for layered windows. The program runs in the system tray and screen captures can be triggered via keyboard shortcuts.The author has some other freeware too, so check that out as well.
