How do you handle image hosting?

I would like to start using floorplans/maps with various device actions on them. This means I need locally stored images, that can be seen over the network. I managed to upload images to HA, but as they need to be accessed with a token, I either need to refresh the token every day (no), or have an image with a long-lived token (also not a good idea).

How have other people done things? Is it worth spinning up an http image host? Or maybe throwing files into an nginx folder inside HA?

Thoughts on a postcard :)
