I just found a cool new feature (I think it's new) in the Office 2003 beta. When you are attaching photos to an email to send it to the folks, you can resize the image instead of sending a half meg file. There are 3 options:
Small:448 x 336
Medium: 640 x 480
Large: 1024 x 768
You can access this option by viewing the attachement options or it will pop up when you right click "send to > mail recipient" on an image file. Very nice feature, kudos to the Office team.
