How do I... Add image thumbnails to Microsoft Windows Explorer?

Windows Vista has an additional way to view thumbnails in Windows Explorer. Click Organize | Layout and choose to add the Preview Pane. That selection will add an area to the right of the display where a larger thumbnail of each image will be displayed as you highlight it.

Once again remember the caveat -- thumbnails take up resources. Be careful how you use them. And if there comes a time when you want to turn them off, just do the opposite of the procedures described here. In Windows XP you would also want to delete the Thumb.db file in each folder.
