If you are on a smaller instance you should probably ask the admin(s) if they are okay with something like this, it would put a lot of extra strain on the server and might overload small instances.

I like this idea, I’ve been thinking about running my own private instance but decided against it as I like the main feed with many different communities that larger instances offer.

Is there a copy or just a reference to the original instance?

My understanding is that the actual full size image is held just on the source instance, but that thumbnails are cached on other instances for a time.

But looking into the official documentation there seem to be json files missing and the descriptions are not completly clear: https://join-lemmy.org/docs/contributors/05-federation.html#post

And just looking around using inspect element to see the HTML source it seems that even the thumbnail is not cached for external directly hosted on lemmy image posts. But then again I also could the the preview of a image post earlier while the full size image was not visible as the hosting lemmy instance was offline.

Do non-US instances have to handle DMCA requests like US instance with european users have deal GDPR requests?
