You can easily take a screenshot in OS X with a few simple keystokes:
“shift-command-3″ will capture the whole screen and save the file on the desktop.
“shift-command-4″ will capture the area you select with the cursor after pressing the keys and the file will be saved on the desktop.
You can also hold “ctrl” when taking the screenshot to place the file in the clipboard instead of saving it on the desktop.
These simple but very useful features are actually one of the things i love most about my new mac. You can basically get a picture of anything online without having access to the actual picture.
