screen+capture

//Screen Capture for the Mac// Cmd-Shift-3 takes a picture of your entire computer screen and saves the file on your desktop. In older Mac OS it was called Picture 1. In new OS it's called Screen shot with date & time. Cmd-Shift-4 lets you draw a rectangle around what you want and saves that file on your desktop.

//Screen Capture for Windows XP// Press the PrtSc button on your keyboard and an image of your entire computer screen will be placed in your clipboard. Hold down Alt and press the PrtSc button to capture an image of the active window only. Then you can paste this image into some sort of software that can deal with it. Photoshop or IrfanView are good choices. In MS Office 2007 under MS Office Tools, you can use MS Picture Manager and paste into there. You can paste directly into Powerpoint or Word but you risk losing the capture since you don't have it anywhere as its own file.

//Cropping the image// In Preview (Mac) drag a rectangle around the piece you want to keep, pull down Edit to Crop. In MS Picture Manager click Edit Picture, then use the cropping tool at the right. In Photoshop use the cropping tool in the tool bar. You can also crop directly in Word or Powerpoint.

//Resizing the image// In Preview (Mac) pull down Tools to Adjust Size. In MS Picture Manager click Edit Picture, then resize at the right. In Photoshop pull down Image to Image Size You can also resize within Word or Powerpoint (but it makes the file much bigger)
