Well shortly after I posted above, there is not custom field posting. It’s just a broken URL. I’ve attached a series of images I hope someone can understand why this isn’t working.
code to post independent of functions: this code is within a ‘front-page.php’ template. No different than these instructions: https://www.advancedcustomfields.com/resources/image/ and code examples https://www.advancedcustomfields.com/resources/code-examples/
code in functions: the code you provided above
custom-field: the custom field’s settings.
