first you need to put the picture in places like
photobucket..
then after that, you need to get the url of the picture.. usually
it looks like this:
http://www.photobucket.com/picture.jpg
then at both ends of the url, add [ img ] and [ /img ] without the
spaces in the square brackets..
click on preview to check..
if there is a picture, it's is up and can click submit
