[Solved] Stop Lemmy from mirroring link images (swg-empire.de)

submitted 2 months ago* (last edited 2 months ago) by [email protected] to c/[email protected]

10 comments fedilink hide all child comments

By default Lemmy seems to be mirroring every link's preview image. Even when that link was originally posted on an external Lemmy instance. That can put quite a strain on small servers. Is there a way to disable this? Ideally I would have pict-rs just be used to host the images my users upload and nothing else.

Solved:

Add

  pictrs: {
    image_mode: "None"
  }

to lemmy.hjson.

See the config.hjson for image_mode

Great! Thanks!

Now I just have to somehow prune the old images...

[–] [email protected] 3 points 2 months ago (1 children)

I think there's a guide for that somewhere? Maybe I can try looking for it tomorrow if no one else finds it first. I think the admin control panel that shows uploaded images might also show the federated ones?

Maybe pictrs does it by itself. It's still working like crazy after I did the change without any user-uploads happening.

this might help https://monero.town/post/2020876

I guess you could call GET /internal/hashes?{query} to see all the images

is the default thumbnails?

[–] [email protected] 2 points 2 months ago

the default appears to be StoreLinkPreviews in v0.19.8

https://github.com/LemmyNet/lemmy/blob/0.19.8/crates/utils/src/settings/structs.rs#L85-L88

but in the main branch it's ProxyAllImages, so I guess that'll be for a future release

There was a post on [email protected] recently about pictures management, maybe that can help

For anyone curious, I think that is the post: https://lemm.ee/post/53212164

Indeed, thanks!
