How to display image that is added to site.txt from blueprint panel?

Using Kirby 3.5.

site.yml has:
width: 1/2
type: files
max: 1

Variable in site.txt ends up as:

- logo.jpg

Where would I look online to learn more about how to display images and such like this from variables in blueprints to showing them in the template? If it’s a random image file name being assigned in blueprints I have no idea how to do this.

For every field we have an example of how to use it in templates/snippets, in your case, it’s the files field:

Thank you. That worked.

I’m trying to figure all this out in order to get a concept theme working since it disturbed me how much I’m depending on a paid template getting updated or not. It is getting updated so no worries there…but I’d still like to have something on the backburner if It came to it.

For other readers it should have been an easy fix I missed:

<?php if($image = $site->websitelogo()->toFile()): ?>
  <img src="<?= $image->url() ?>" alt="">
<?php endif ?>
