Add a button to a portal row
How do I add a button to a specific portal row? I want to be able to add a button to each row in a portal that will take the user to a larger image. I have a collection of LP record albums. I want scans of the record labels and front and back covers. I created a portal and each row is a different picture for the same LP. How can I add a button to take me to a larger view of the same picture?
