If anyone needs to delete offline images stuck in the bin...

[xgrimx]

Open a command window and enter this:

docker exec -it immich_postgres psql -U postgres -d immich

This will run PostgreSQL inside the immich container (immich_postgres) and connect to Immich's database.

And run:

DELETE FROM assets WHERE "isOffline" = TRUE;

That's it.

Such a bless to manage external galleries but this can happen if you remove the mount. For some reason, I couldn't find anyone here solving that without any complex script or nothing at all. I'd swear there was an even easier way to do this with a docker compose command but I completely forgot lol. Anyway, hope this helps.
