I setup a hidden service for image hosting a few days ago. It had security features to prevent IP leaks and entry guard identification, though I won't mention the specific features for obvious security reasons. I still took it down though. Honestly, I'm not comfortable running a hidden service until we find out how Marques was identified. I also don't have the resources to host the entire Tor or even SR community's images if it became the default image host. I also don't have the time or energy to police it for the massive amounts of CP it would get if it became the default image host. Most people here are not technically savvy enough to run their own hidden services safely. Honestly comsec, it's a bad idea to suggest it to random people. They are going to get themselves into trouble. However, there are technically savvy users here who could consult anyone who has the resources to take on the challenge of running (potentially large) hidden services.
