Stanman, first you have to have the picture on your computer (scanned or placed there by a digital camera, etc.), then make sure it is no larger than 100000 bytes (may need some kind of photo manipulating software). Then when you either reply to an existing message, or start a new message, click on the "I want to preview my post and/or attach a file" box just above the "Continue" button. Click on "Continue", then enter the file name and path in the box (or do as I do and click on "Browse", find the file on your computer and open it and that'll enter it in the box). Then click on "Continue" again and you're done.
