Different versions of Mac OS X have different formats for screenshots.
The default screenshot format can be changed, by opening Terminal (located at /Applications/Utilities/Terminal) and typing in:
defaults write com.apple.screencapture type image_format
Where image_format is one of jpg, tiff, pdf, png, bmp or pict (among others). If you omit the second line, you will need to log out and in again for the change to take effect.
Grab and Preview
Instead of using the keyboard shortcuts above, screenshots can be taken by using the Grab application included with Mac OS X. It is located at /Applications/Utilities/Grab. Some versions of the Preview application have an option under the File menu to take a screenshot.
From the Terminal
The screencapture command in the Terminal can also be used to capture screenshots, and is useful for scripts. Here is an example.
screencapture -iW ~/Desktop/screen.jpg
