My concern there is my understanding has always been that WhatsApp implements end to end encryption through the Signal protocol, how can images be stored and be considered end-to-end encrypted? So are only text messages end-to-end? Ignoring logs being uploaded to the cloud.

I wouldn't send any sensitive pictures over WhatsApp then.

Because the actual data for those images, that is stored on Facebook's media servers, is just a blob of ciphertext. Only the sending and receiving clients actually have the keys, not the servers.

E2E encryption doesn't mean P2P networking. Data still flows through servers.

Probably blob store, not just image store.
