It doesn't. It's hidden to everyone but you. In your Dropbox folder, right-click the actual JPG file and then choose "Dropbox > Copy Public Link" and then post that here.
The slideshow option on your website still doesn't bring us to the full size file. We need to see the entire 2499x3733 pixels of your original submission. (I can access your rejected photo but no one else can)
