Does Lemmy automatically purge old cached images? (lemmy.asudox.dev)

I just noticed that my pictrs image volume reached 20 GBs in size. Does Lemmy or pictrs not delete the cached images automatically after some time?

I just changed to another distro (so I had to set everything up again) and I simply did not backup the pictrs volume because how much time it would've taken to transfer it from one machine to another. And well, it seems like what you said is not true. I can load any old post and I will still see its images.

The proxied images will be refetched from the origin if they cant be found locally. There should also be a configurable maximum size for the image cache but I dont see it mentioned in the pictrs readme. So like Dessalines said you need to ask the developer directly.

Pictures you (or your users. if any) uploaded yourself should be gone, though.

I've turned off proxying myself and purged what I could find from pictrs and it's still taking up way more storage than it should. And it's a messy black box where I have no idea what's really going on. Another reason why I want to switch to Piefed.
