Screencap Freeware - FastStone
I’m have always loved Snagit made by Techsmith, however my current computer didn’t have a working license of the software. So I was forced to find a decent second place application.
Enter FastStone - makers of ScreenCapture. I love it. Lightweight. Has all the pre-built functions of crop, resize, rotate, adds captions and callouts, and best of all, is free. Excellent app.
The only thing I couldn’t do was take a screencap of the application’s interface.
So I guess you will just have to download it.
