Change the URL on the Blog Inage. on Collection Page

I'm trying to change the URL on an image on the collections page of my blog. Currently it goes to the blog page on my site for the post. I'd like to change that to go to the original post on Linkedin. Is that possible?

All other hyperlinks on the blog post are set for the original post. I'm working off of 7.1

When you add a blog post, it has an option: Source URL.
