Why would this need cloudflare tunnells? Why are you not using free-tier everything and hosting image separately on some third-part CDN

I am using free tier, cf tunnels are included in it.

Ok, what is the hosting bill coming from? what is the setup like? is it something like monthly VPS contract and you can't automate it with recurrent payment (like e.g. prepaid yearly plans or something)?

Protip: the most cost will be from your CDN images, just allow something like imgur/postimg embeds and it will greatly reduce bandwidth costs for the server.
