EasyCapture lets you capture screen images in a variety of sizes and formats. This free program adds a few nifty extra functions, too.
To nab a screen with EasyCapture, you select the desired area type (full screen, region, window, and so on), move your cursor to select the area, and click. Thanks to a tabbed interface, you can take several screenshots in short order and deal with each at your leisure.
A smattering of graphics tools lets you perform simple tasks such as adjusting brightness and contrast; converting to grayscale; and adding text and simple included graphics such as lines, arrows, and word balloons.
You can save your work as .bmp, .gif, Jpeg, .pcx, .png, and Tiff files.
A great tool for capturing screenshots.
