HA has a "www" folder that by default that is accessible to the network. Anything in /config/www appears at http://yourhassaddress:8123/local, so your images will be at http://homeassistant.local:8123/local/image.jpg

Home Assistant is open source home automation that puts local control and privacy first.
Powered by a worldwide community of tinkerers and DIY enthusiasts.
Home Assistant can be self-installed on ProxMox, Raspberry Pi, or even purchased pre-installed: Home Assistant: Installation
Discussion of Home-Assistant adjacent topics is absolutely fine, within reason.

Aha, that was what I was after, big thanks!
So, after a bit of meddling:
The location I was placing things in was media>my media (from the HA UI).
Assets there are stored in /media, and served in 8123/media/local, but require an autoSig.
Changing permissions doesn't affect the availability, no sig is a 401 error.
However, if the file is copied from /media to /config/www/ , it's then served (as you said) under 8123/local.
Brill, not too painful a process for a few static images (or indeed if I'm feeling brave, I could just symlink the folders).
Maybe one day there will be a way to upload background images for picture elements cards from the UI :)
If you're using HAOS (ie not running in docker), there is an official add-on called "File Editor" that allows you to edit the config.yaml and upload files from the UI. It's not perfect but gets the job done.
That's a very good shout, as it'll save me mucking about in bash.
I use Immich.
Gotta be contrarian here and say: using floorplans as your graphic frame for controls is very inefficient. And not very good graphical design.
I can appreciate that!
I do have standard layouts which are mostly big button to do a thing in the room.
But I also fancied having by-floor layouts.
And you're right: The button I have that sets the kitchen spots on/off/dim as a group is 10x more useable than a scale representation of their location in the ceiling!
How do you have HA set up? For example I currently have a Raspberry Pi 4 and installed a HomeAssistant Docker image.
Since I'm not using HA addons, I'm free to use any Docker image that supports Raspberry Pi's ARM architecture. I use a simple file server which is more than enough for my needs.
If you're using an HA setup where that's not possible, someone else may be able to suggest an HA addon that would fit your needs.
HAOS under proxmox.
It's definitely one of those "many ways to skin the cat" situations!
Ah yeah, I've heard of Proxmox but have never looked into it. From my experiences, HA is quite flexible so some questions are never that simple. Still worth all the effort though :)
Why not just run another VM/LXC with nginx in it? Super easy.
That was going to be my backup plan, as I didn't want to use any more resource if I could avoid it 😅
The good news is, we figured it out, and got the file serving out of /config/www without an auth requirement.
For many years, I've used Weebly to host images, docs, etc, on our website URLs, but they're just static. When I need to do work on my phone or laptop and need that synch'd elsewhere, I use the Microsoft suite, but those are normally Excel charts or Word docs.
I'm more interested in what people are doing for internal hosting, not external hosting services. Thanks for the info, however.
Lots of localcloud solutions have S3-compatible features. There's also MinIO, Garage or Zenk if you just want to do it yourself.
