PokIt

PokIt is a curious screenshot captor featuring a very low resource consumption that allows you take screenshots easily.

You'll only have to press the 'Print Screen' key or assign any other hotkey and then, choose the rectangular area you want to capture.

The new feature that makes it stand out from the rest is that it offers you the possibility to upload those new images to the Internet.

Choose the image format and then choose whether to keep it in your HD or to upload and share it on Facebook, Twitter or send it via email.
