I'd like to create modal image popup that will show customers the size charts, the way they've done it here: https://www.piperloucollection.com/collections/apparel/products/not-slim-kinda-shady?variant=2366210...
When you click on "View Size Chart", then you'll know what I mean.
I tried following this tutorial: https://shopify.dev/tutorials/customize-theme-add-size-chart . It worked and all, but instead of the actual size chart loading up, I'd like to load up an image from my Shopify files.
My theme is Debutify.
