Displaying images in a page folder

Hi. I'm pretty new to Grav and I'm trying to display a header image from a file upload in the admin panel in a template. The idea is to upload the image to a folder within the specific page folder (the one that contains the md file) and not a centralised image folder. This way all the content for that page is together if I need to move or delete articles in the future.

YAML:
header.background_image:
type: file
label: Photo image header
destination: 'self@/header_image'
multiple: false
accept:

• image/*

TWIG:
{% for image in page.find('header_image').media.images %}
{{ image.url }}
{% endfor %}

This displays fine when I've linked to a folder relative the the user pages folder, but I can't seem to get it to work in the above example. Am I missing something?

Thanks.

Hey, Michael! Glad to hear you are trying out Grav!

What I would do in your situation is something like:

<img src="{{ page.url }}/{{ page.header.imagename }}" />

and add imagename in page header including the file extension.

This is just a crude example of doing what you need to do, but there are much more ways to customize it to just your needs. What I experience to work great for me is to do the simplest method first, do a note of it and improve it when I have nothing more important to implement it. This is of course if you don't implement it on a high traffic website which requires more load freiendly methods,

Good luck and happy Graving!

Thanks for the quick reply, but I can't see your example in the above post.

Sorry, I forgot to format it as code... My fault 😊

To explain what this does:
It takes the page URL and adds the filename which it gets from the page header.
So in frontmatter do:

---
title: Test title
imagename: testimage.jpg
---

Brilliant, thanks for this. After hours of looking I also found this (doesn't add to folder rather than targets the image directly from the admin upload:
{{ page.media[header.background_image|first.name] }}

Which I'm going to turn into this for a tasty background image:
{{ page.media[header.background_image|first.name].cropResize(2400, 1350).url }}
