Interesting that he uses.some ext service for caching the images. Doesn't this creates a security issue with ext content? Shouldn't this easy to Selfhost through some nginx config? Like nginx do a proxy pass upstream and cache and return a cache header? The only thing you need to do is either use a specific path or do the same as this service does with a URL at the end. Of course denying random hosts l. Should be doable in a few minutes
