Topics could include (this list is not intending to be exhaustive — if you think something is relevant, then please don’t hesitate to share it):

- Server maintenance (updates, scaling, etc.)
I don’t see how it’s a privacy risk since you’re not exposing your IP or anything. Likewise the images are already uploaded to your servers, so there’s no extra privacy risk for the uploader.
