-self host your own wallet with BTCPay software 
-self host your own image & videos with Chevereto software
-self host you own relay with nostr-rs-relay

of course that cost money, more money than what you are paying but most importantly you need to have the skills to self host everything.

So it's good there is administrators out there running things for us. 
Sometimes it's better and easier to just pay someone else to host and maintain things for you. 

What worries me is that someday the relay operators or image hosting websites might shutdown and there goes all my posts. 

I like hosting my own things.

 Agree, freedom don't come free. I just went with hosting all my images on a public s3 like bucket with a domain pointed at it. I don't host my own relay but I would like a relay or something I can host to pull down all my posts for archival purposes should the public relays let me down. Know of anything like that?
