I don't believe the original Suggestions module as provided by modzzz even posts to the outline.
I don't want suggestions appearing on the outline on my site because the suggestions are meant for Admin's eyes only. Not so Answers.
I'm positive I posted a suggestion with a photo to this site some time ago and the photo appeared in the outline. I just went through the Outline and it seems that the photo didn't make it after all. I thought it did. Sorry.
