How does image uploading work on Lemmy? (vlemmy.net)

When you upload an image in the URL bar when creating a post, where does it go? Are they hosted on the respective Instance of the community?

As far as I can see, images aren't federated, only a link to the image.

When I look on my server in the volumes/pictrs folder, there are a LOT of images that I recognize from my feed. They are not from posts posted to my server but belong to posts of communities that I have subscribed to

Are they thumbnails? If not, perhaps this is configurable... I'll check out my own images folder and see if it's pulling them in, but it definitely shows the remote url for images when I'm viewing them on my instance.

no, a random image I just now check was 3.3mb even. But you're right, the image source does point to the origins server location... Then why are all those images stored on the server ?

OK, I've just realised something new - images pulled from websites as thumbnails are uploaded to the server and appear to be basically full sized, i.e.:

https://agora.nop.chat/pictrs/image/59cfdd9c-2f69-4e8d-8afc-6fbc0c1cca87.jpeg

This image is on my server, but it's just pulled from the website as a thumbnail. This doesn't seem to be super consistent in how it's handled - I'm continuing to look at what's causing it and why it doesn't seem to happen all the time.

EDIT: Seems like there's more on there than I expected. Gonna continue digging.
