I did not know, you were talking about
OS X 10.8 Mountain Lion and not
Mac OS X 10.7 Lion. In

PS: You can crop screenshots via Preview or use CMD+SHIFT+4 (> Spacebar > click window/element) to select what you want to shoot.
PPS: For images wider than 800 pixel, please use the TIMG tags instead of the IMG tags by just adding a T in front of the [url= and closing ]Image[/url] tag, like [img] and [/img] to prevent horizontal scrolling.
You can use the
Image to edit your images and add the Ts.
