When trying to GET an unexisting item, a 200-OK is returned even if the file doesn't exist

To Reproduce
Trying to do this:

const url = `${serverUrl}/random_sha256`;
const response = await fetch(url, { method: 'HEAD' });

either with HEAD of GET will return 200-OK. I think the problem is that the server is returning a picture correctly:

Yes, I’m aware that it always returns 200. This is intentional because if I return 404 along with the "not found" image, many Nostr clients display an error on the screen instead of the fallback image. So far, I haven’t found another way to "force" this image in all scenarios.

I also know that in the case of a file, video, or other file types, this behavior is not ideal either. For version 0.7.0, a dynamically generated "not found" file will be returned for each accepted file type. I’m experimenting with it.

[ktecho]

Yeah, maybe an option in Setup to choose the behaviour, because right now there isn't a way to know if a file is present in the server in a programatical way, right?

It looks like an easy fix. Change a number here. This might not be desirable for all users but if it's helpful for you, @ktecho, ...

As for the project merging this: I think it should signal 404 or provide an endpoint that allows checking availability of files. As @ktecho implied, as a compromise it could return the 404-image with 200 status on GET but the 404 status on HEAD.
