Just remove the XXX from the first image tag (be sure to enclose it and the closing tag in square brackets, don't forget the slash in the closing tag, and don't put any spaces anywere in the line.
You also have to add .jpg (including the period) to the end of your URL, just before the closing [/image] tag.
Also, you have to unlock your photopoint.com account. When I tried to display the image for you in this e-mail reply, a dialog appeared asking me for your password. If you want people to be able to see your photo, it can't be password protected.
