Jim,
All the images for My Home Course are set at 600 wide by whatever tall. (usually its 600 x 400)
Resolution, try to make at 72 dpi. This way it doesn't overload anyone's system. If you want, send them to me so I can prep them for Ran and get them back to him in good time.
Send them to: tommynacc@gmail.com (My new main email address)
