I think https://fission.codes/ecosystem/wnfs/ https://fission.codes/ecosystem/wnfs/ might do what you want (though I don't know about viewing photos in browser etc). Alternatively, IPFS supports unixFS and a mutable filesystem through the desktop client if you are happy to host them on your own machine (it acts like a unix dir) edit: ah sorry, I see you actually asked for a private network. You could possibly look into https://ipfscluster.io/ https://ipfscluster.io/, though it might be a little heavyweight for what you're looking for
