Bergermeister:
From this site's FAQ:
Images can indeed be shown in your posts. However, there is no facility at present for uploading images directly to this board. Therefore you must link to an image stored on a publicly accessible web server, e.g.
http://www.some-unknown-place.net/my-picture.gif. You cannot link to pictures stored on your own PC (unless it is a publicly accessible server) nor to images stored behind authentication mechanisms such as Hotmail or Yahoo mailboxes, password-protected sites, etc. To display the image use either the BBCode [img] tag or appropriate HTML (if allowed).

In my own words:
First, you're probably going to have to upload your images to an internet image site. I use Sony's Imagestation.
Once you've uploaded the image, go to it and right click on it. Select "Properties." Highlight and copy the URL address in properties. See the box above the widow you open to post on this board marked URL? click it. This will appear:[url]. Paste the URL address that you copied from your image next to it. Then click the URL box again and post.
I think that's all you need to do.
