Most people have received an occasional email with an image so large it stood out from the message in every direction. When megapixel snapshots turn into mega-sized graphics, you may wonder how to include them in your own outgoing messages without overwhelming your recipient.

Downsizing images for use in emails need not be an arduous task or involve complicated, slow-to-launch software. Most of the image resizers applications you can download from the internet work in a similar manner. Image Resizer for Windows is typical.
