Upload the photo to the Photo Gallery (link at the top of the page then select Upload File at the top of the Gallery Page). Then click on File Information for the file you just uploaded and write down the photo's URL which is listed beside "Filename". Go back to this thread and click on "New Reply". Just above the box where you post your reply will be a row of icons. Close to the center of the page (right to left) you will see an icon that looks like a little painting with a + sign in the corner, that allows you to insert a photo. Click on the icon and a dropdown box will ask for the URL. Type in the URL you wrote down earlier. Then click "insert" and the photo should be inserted into the post.
