Help Appreciated-Image (Zoom)

[a11ecaty1]

I'm new to FileMaker. My version is FileMaker Pro 8.5, I know it's kinda of old. Any help would be greatly appreciated. I have surfed through various forums and nothing has helped.

Question: How do I zoom in/out on specific images? Whether it's just one picture or when it's a thumbnail such as in "Asset List View" ?

Details: I'm using "Lending Library" as a starter template and reworking for cataloging artwork. Please be detailed and specific with instructions. I know nothing about scripts so if they are involved, it would be great if someone could provide step by step instructions. Below are some thumbnails:
