The 2nd image post is meant to be the same as the fist, but with the text of the ISBN numbers as part of the post. The bulletin board URL is not processing my syntax as I intended. I think the bulletin board is in error.
It looks like you've tried to post an image url into the url. It should be: [ url = paste the link here] write the words to appear in the window here (so in your case the ISBN [ /url ] Without any of the spaces.
I'm not sure that is possible. The closest would be to show an image and then use a URL link underneath with the words - ergo an embedded image and then a normal hyperlink.
