How can I enlarge embedded Buy Button images on my website?

Hi there! I have a website I’ve built myself from the ground up and have created my store within the site using embedded Shopify “Buy Buttons”. The problem is, when a user clicks the button on an item to view the item details, the images are way too small. There’s plenty of room in the pop-up for the main image to be larger–it’s surrounded by tons of whitespace! Is there a way I can edit the javascript so the image fills the available space in the pop up? I attached a screenshot of the way the popup looks now, and an image where I’ve edited it to show how I think it should look. Thanks for anything you can do to help!

I should add my url: www.vibrata.com and a direct link to the store is shop.vibrata.com
Thanks!

Hey @Vibrata
Kindly share your Store URL and Password if enabled

Hi, like I said, my website is custom made by me so I can’t use the Shopify Store API. I need to use embedded Buy Buttons.

Hi! Do you have anything for me to try?
