When you click "Post Reply" and you get the text box for writing your post/message, scroll down the page a bit more and look for the gray button that says "Manage Attachments" click it, another window will open. If you've got the picture on your computer you will want to click one of the "Browse" buttons in the new window, navigate to the picture on your computer, select it, click "Open", click "Upload" on the window that popped up for managing attachments. After some time, that window will refresh and your image file will be listed. Now you can click "Close this window" in the top right of the recently refreshed window, and you will be brought back <<here>> to the text box for writing a post/message. Just click "Submit Reply" as you would do normally and your picture should be at the bottom of your message.
