I went ahead and did one of the pictures for you. You should replicate how I did it with the others. You should always use the [img] tags and link the picture right into the post because most people do not want to click 30 different links to view a boat. To get the raw image for the pictures, go to the shared files link, then right click on the image there and click on "Show image in a new tab" and then use that link. Should look something like this:

Boat looks nice! Unique design, nicely executed. I saw you building this a few times and saw your 10 step plan.
