Hi Spike,
You might be clicking on the wrong code in photobucket... once you post a photo on that site, you'll see some link things below your photo -- URL, HTML, and IMG. Click on the one that says IMG and it should automatically copy it. come back here, open your mesasge, and right click in the white space. Select "paste," and it should paste the link in the message. The photo won't show up until you preview or post the message, though.
