How will we deal with all the broken images?
When an instance goes down, all of the images on it go with it. there's going to be a lot from lemm.ee, especially given its size.
You're viewing a single thread.
Images dont get saved locally on other instances if they host the content? Well that seems like a big flaw in "federation"..
I assume it's an intentional trade-off by the devs to reduce the storage burden. If each instance is a complete mirror of all federated instances then hosting becomes that much more expensive.
It's also an avenue for attacks.
Instances have 3 options. Save it locally, proxy it, or do nothing. Saving every federated image is not feasible for small instances. It's not a fault of the protocol that instance operators don't want to pay a thousand dollars a month for storage. Matrix has this problem, and look what happened to them: tiny instances are expensive to run, so don't flourish.
Not really, it means I can't send every lemmy instance csam.
Depending on how the admin has pict-rs (the "subsystem" it uses for media) configured, post images can create local copies /thumbnails for image posts. Some instances opt to do that, some don't.
Other images like ones posted a comments, user/community avatars/banners aren't stored anywhere except their home instance.
But yeah, even the limited caching has proven problematic if questionable/illegal content gets posted.
