Found it: https://lemmy.dbzer0.com/post/17357923/9209304

On 0.19.3, you can:

• Limit the file upload size for local users through nginx configuration
• Disable incoming federated images through Lemmy configuration: https://github.com/LemmyNet/lemmy/blob/main/config/defaults.hjson#L49 (set this to false)

Additional: On https://github.com/LemmyNet/lemmy/blob/main/docker/nginx.conf, there is an option “client_max_body_size” that you can set to 0.

Where can I find that option? Is it during instance-setup?

Well, both. I want to grow my instance a bit and also don’t want other people to post weird stuff in my communities

Interesting idea, thanks

Yeah :+1:

oh ok. Thanks :)
