PicPick is a wonderful free alternative to SnagIT. When hunting for free Screen Capture tools, got really impressed with this small and free tool.
PicPick provides the following ways to capture screen:
- Full Screen
- Active Window
- Auto Scroll
It also includes a Image Editor that allows for annotation, basic image editing, exporting and sharing.
It also provides, zoom, whiteboard and crosshair to be used on the desktop. Worth the try!
