How do I link back to the main story from a picture?

Example – this picture:

https://www.celebslam.com/celebrity-halloween-costumes-2006/elisha-cuthbert-halloween-costume/

I want to provide a link back to the main story at the bottom of the picture:

https://www.celebslam.com/celebrity-halloween-costumes-2006

I get a lot of searches from Google that lead to individual pictures on my site. I think some of these searchers don’t know that the picture comes from a main story–because there’s no link.

Thanks for any help you can provide!
