It does the same to my posts. I would type in Word. I would paste to the forum and hit preview. Pic is there in preview. but when i post, it adds an additional URL to the pic. I have to delete one of them for the pic to show. I upload my pics to the E wiki and then hotlink them. Maybe that has to do with it? E sees the file name and does you a 'favor' and adds the full URL?
