Nato... stop trying to combine bulletin board codes with HTML codes... they won't work together. Your not write a web page. Its a lot easier than what you think it is. Also, you need to get the url of the photo not the url of the page to post a photo, and this is done by right clicking on an image. To get an idea of how Chris did it click the "Reply with quote" link and what he wrote will come up so you will see what he did.
IF all else fails, and this is for anyone not sure what to do, click the "Reply" button at the bottom of each page and use the buttons at the top of the composition box so that you will be able to get the format right. It really is not hard to do once you get a basic understanding of it.
