If you just posted a photo and you want people to see it, this is the trick you gotta follow. First, find an image you want to use for your Story. Then, upload it to your Story and save it. Upload the new post you want people to see to your Story. Then, add in the image you just saved from your Story. Make it full-screen, and this way anytime someone taps on your Story, they will be directed to your post.
