FastStone Capture is an effective and simple tool to make all those screen captures you need when performing a job, creating a manual, getting a photograph off your favourite game, etc.
It will no longer be necessary to go into third party applications in order to get the screenshots, and much less in order to resize them, as this programme allows you to select the fragment of the screen you wish to capture and will then take care of the adaptation.
When the programme is run, it places a toolbar (on the lower right hand corner) and to be able to activate some of its specific options, it is just necessary to right click on them.
The options you can configure are very simple, any average user will be able to make use of them, even if they do not have any previous knowledge of this type of programme.
FastStone Capture is an application worth trying.
