This is my test of the process for creating a "Click to Enlarge Photo" link recommended in this posting. Since @majes.tytyty wasn't sure if the process would work in the Safari browser, and that is my primary Steem browser, Safari is the browser I used to test the process by making this post.
In the photo, I rub the chin of Cocoa, a family cat. I took the photo. If the recommended process works correctly when the Safari browser is used to make a Steemit post, then you should be able to enlarge the photo by clicking on the link directly beneath it.
EDIT: The process did work.
I hope you enjoy the photo!
