Recently started work on a BigCommerce project and on the homepage I want to have a theme area where normal site admin users can upload their own images based on holidays (Xmas, halloween etc) in the theme editor.
I know how to add in some custom elements in the theme editor using the Schema and Config files (headings, text, font colours etc), and how to reference them in the homepage. I'm also fine with referencing set images in the assets folder which aren't going to change, and manually coding references to them.
However I can't quite seem to work out how to add a custom image upload to the theme editor, or how to reference it in a page. Can't seem to find any answers in the Stencil documentation or usual Google searches etc either.
