Add book cover to book record > Likes and Comments

I created a book record but accidentally neglected to include the book cover. How can I add the book cover to the record in such a way as to end up with only one record—the one that has the book cover? Thanks!

Here's the book's author: Jennifer Moe Taylor

Here's the book record:

And here is a site with the book cover:

It looks like this problem has already been solved. Thanks to whomever added the book cover to the record!
