Pass image to k-collection

I’m currently building a custom panel section to display a number of links. I cannot quite figure out how to pass an image to the <k-collection> component.

This is my Vue file for the section:

<template>
  <section class="k-links-section">
    <header class="k-section-header">
      <h2 class="k-headline">{{ label }}</h2>
    </header>
    <k-collection :items="links" :layout="layout" />
  </section>
</template>

<script>
export default {
  data() {
    return {
      label: "",
      layout: "list",
      links: [],
    };
  },
  created() {
    this.load().then((response) => {
      this.label = response.label;
      this.layout = response.layout;
      this.links = response.links;
    });
  },
};
</script>

And this is the PHP file:

<?php

return [
    'props' => [
        'label' => function ($label = 'Links') {
            return $label;
        },
        'layout' => function ($layout = 'list') {
            return $layout;
        },
        'links' => function () {
            $links = [];
            $blogPosts = page('neuigkeiten/blog')->children()->listed()->filterBy('intendedTemplate', 'post')->limit(3);
            foreach ($blogPosts as $blogPost) {
                $links[] = [
                    'icon' => 'page',
                    'link' => $blogPost->url() . '.social',
                    'target' => '_blank',
                    'text' => $blogPost->title()->value(),
                    'image' => [
                        'query' => $blogPost->thumbnail()->toFile(),
                        'cover' => true,
                    ],
                    'info' => 'Blog'
                ];
            }
            return $links;
        }
    ]
];

The list of links is rendered correctly, but I only get a black square where the image should be. I am not sure how the array where I pass the props to the Vue file should look. Anyone have an idea?

Okay, I found out that the k-item-image component expects a src prop.
This seems to work:

'image' => [
   'src' => $blogPost->thumbnail()->resize(120)->toFile()->url(),
]
