Both are still decentralized but 3Speak is bringing out a new system that will decentralize the video hosting in a manner like you described by having individual hard drives seed the videos.

Fixed it for you.

3Speak is addressing "only" videos but should probably do the same for image hosting as well. The same infrastructure and incentive program they build for videos could probably work well for images and would solve our dependency on centralized image hosting. Who wants to read a 100% text post, after all images are deleted due to censorship attempts by the government?

Image hosting will be tackled as well, as thumbnails are used extensively on 3Speak. Both image and video will be handled by the 3Speak desktop app in a decentralized manner.
