So I am thinking about loading a series of images one by one for the user in the browser.

Would I go about this by opening a socket and request the images one by one with a given (slow) interval? Or would you say "Why not just make it a video and use all the advantages that this already has for browsers"? (Since a video is also just a series of images)

I want to stress that I would like to get them in a slow interval, so hopefully it won't create any stress on the client or the server.

What would be the best way?
