I don't see the file/picture attached to your post. I am attaching a picture just as a test to see it works to attach pictures/files to post. Although picture may inspire ideas, it is not meant as an answer, as I would need to see your pic/file first to possibly have a solution.
I think you may have forgot to click little "Insert Image" icon after choosing file, then uploading. the final step would have been insert image into post, display link, etc.
