Hi Threehorn!
Welcome to the Gang of Five!
In order to get screenshots or whatever pictures to this board you can either attach them right from the harddisk to a message (you'll find the link to do that bellow post icon list), but this woks only for pictures up to 800k size (not that many pictures are considerably bigger). Or you can use the image (IMG) ling above. Click it and enter the url of a picture elsewhere and it should appear in the message.
