You should be able to edit your story and add the photo to pop up in it.  There should be a bar above the text with a box that you can click on at the end of the toolbar, it will bring up your photos, click on the photo and that should do it.  I hope that helps.  Once you get  your photos in the story to pop up, people will check it out and comment.  Its a pretty path, looks like a nice place to walk.  :o)
