My first question is where are embedded content like photos or videos stored? Are they on the server where the content originally sits making only a link or sitting on the blockchain?
My initial experiment would make me think the images sit on the blockchain. First off, I embedded one of my own photos from imgur into a blog and posted. I then deleted the photo from imgur, but the image is still showing in the blog which means it is more than just a link and must be sitting on the Steemit server side.
Secondly, Steemit does not seem to allow me to delete an image from my own blog when I try to update the post which is curious. This would have implications for copyright if one was required to delete content for any reason.
I don't really understand blockchain technology so much but if embedding images and video are more than just linked code would this have implications for the scaleability of the technology?
