Cropper is a nice software by itself, but its functionality might be significantly improved by installing free plug-ins. Some of them:
AnimatedGif - Captures to an animated GIF image.
AviFormat - Captures to an AVI movie.
CountdownPng - Gives you a countdown before taking the shot to allow you to set it up.
SendToEmail - Sends the image via the default e-mail client.
The mentioned and other plug-ins can be downloaded from the following link:
