The feature

Hello,

First, I want to express my appreciation for Immich — it's amazing!

I’m the main developer behind Wallpanel, an addon for Home Assistant that includes a photo screensaver and integrates Immich as a potential media source. Wallpanel operates as a JavaScript app in the browser and interacts with the Immich API.

Currently, since the Immich server doesn't send CORS headers, users must set up a reverse proxy to add the necessary CORS headers for functionality.

It would be fantastic if the Immich server could include CORS headers and provide an option to configure the Access-Control-Allow-Origin setting. This would simplify the setup process significantly.

Thank you for considering this!

I don't think we will plan to add this. We purposely keep the web service as simple as possible and delegate these functions to a trusted reverse proxy.

Thanks for the quick answer!
Unfortunately, many users are overwhelmed with setting up a reverse proxy and configuring it correctly.
I think that the implementation would not require much effort.
Would you accept a pull request for this?

You could ask on #contributing channel in the discord if a PR would be accepted. I would suspect not.
