Explain the difference in hosting content on a server vs downloading and hosting it local to be rendered by a browser ? The number of people in the audience its being shared with ? If I show someone what I have locally I have doubled that audience. Remember the double a penny math ? If everyone shared a photo with 1 person effectively doubling the sharing, in 40 days you are going to have the entire world covered. The entire premise of IP and copyright is broken when it is so cheap the common method of presenting material is to copy it and render it locally.
