Shutter is a feature-rich screenshot program for Linux based operating systems such as Ubuntu. You can take a screenshot of a specific area, window, your whole screen, or even of a website – apply different effects to it, draw on it to highlight points, and then upload to an image hosting site, all within one window. Shutter is free, open-source, and licensed under GPL v3. Shutter is available for any major GNU/Linux distribution and can be installed using your package manager. If you want to upgrade to the latest release.
First of all, install the rpm package using yum command and then simply install “shutter” package.
# yum localinstall http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-1.el6.nux.noarch.rpm
# yum install shutter
